@@nathanielscholtens2812not wishbone, that's correct but that refers to the arms not the suspension. In this case it's double wishbone CANTILIVER suspension
Very similar to a dunebuggy/race car. This is a winning design for a reason. He even has similar components. You can see upper and lower control arms and a spindle attaching them. The rod going horizontal to the frame is similar but not quite the same as a torsion beam which was popular on old trucks and old vw beetles. Basically as the control arms articulate the torsion beam, which is spring steel twists and returns to its original position. Torsion beams were phased out and replaced by vertical mounted coil springs or coilovers. But this design works the best because of its double wishbone design (independent front and rear suspension) I would say the sliding shock is actually like a cantilever suspension as well. They do have horizontally mounted shocks on trophy trucks but it’s kind of overly complex design, and dune buggies, trucks, and race cars all have diagonally mounted coilovers on the a arms now.
I feel like you would get better results if you used a larger tredmil for more varied terrain. Also trying to combine suspension methods. The idea being that you impact a soft suspension and then a hard suspension so the whole ride is smoother than with just a soft suspension or a hard suspension.
If I were to get a solution to delivering more, I would just load the stuff and cover it with something so there's no way for them to fall in the first place, but then it wouldn't be a suspension solution testing isn't it hahahahah
I feel like it depended a lot on the stiffness on the suspension. I wish you somehow compensated it so the stiffness would be equal. I think the dampening effect of the rubber tires for example would become more beneficial if you put more weight so they could compress more
Came to say this. The more compliant suspension out performed the super stiff over-sprung suspension. I'd have loved to see the magnets in an independent setup. Also the coilovers should have been brought further inboard on the arms to increase progression.
There is problems with your tests, for example: you're using different length and width wheel-bases for same tredmil, also wheel count. This is causing unfair scores, so efficiency and durability tests are for satisfaction. There are different variables such as: length, width of wheel-base, wheel count, wheel weight, weight of unsuspended part, range of suspension, stiffness of suspension, height of center of mass. Very small amount of those is taken to account. Like, models with long wheelbases is OP for a jump cause they rotate less while riding off a ramp. Also you're tugging from the front instead of from the axis, that is going through center of mass, that causes bounce nomad to flip over! There is so much room for -improvement- part 2!
It would be interesting to see a test of different suspension geometries, like swing axle, double wishbone, mcpherson strut, swing arm etc. And see if you could make anti roll bars and test the difference that makes as well
If you're using spring suspension you always need a dampener because spring will oscillate which causes the additional shake in small bumps test, which in turn makes the carrier less stable. With sort of free floating rubber tires you needed a guide rod in big bump test so that it wouldn't fall over due to tires being carried by inertia tip over the whole cart. And also it doesn't help that the suspension isn't connected to wheels directly. Magnet suspension would work much better if it was stiffer, because it really was too soft. More magnets or stronger ones would make it much more reliable, and also just like in spring suspension it should've had a dampener, which would be easy to make just by surrounding the magnets with aluminium or copper so that they would cancel the oscillations quite quickly. I think the "summit seeker" type worked the best because it was stiff with two rubber rings and it didn't need dampeners because rubber didn't oscillate that much as in "crawl voyager" (which needed a dampener). and as for chain one, well... It's a funnier character than we ever had.
A suspended cart design can be great to keep a load level, but not like this. A big advantage of magnets though in this case is they're really small so can be used in combination with other methods. For example using soft shock absorbers, and adding magnets to make the suspension progressively stiffer.
This was pretty cool. The rubber cruiser was almost like solid axle leaf springs, but with rubber rather than spring steel. The summit seeker was kind of a mix between double wishbone and pushrod. And the spring rover was almost like semi trailing arm.
Super fun! These were variations on suspension geometry as noted earlier but none had dampers. They all had springs. A real damper must allow the spring to compress near its normal rate but then rebound at a much slower rate. This is usually done with one way valves of different sizes in gas or hydraulic shock absorbers. Challenge: Make a Lego shock! I have no idea how!
@@andrewkarsten5268 Sorry I was talking rate of return not spring rate. But the amplitude does not change just the frequency. If it reduced the amplitude the wheel would not return to its original position. Every time a bump was hit the car would get lower and lower...
I like the summit seeker! That design is unique it seems because of the combination of vertical and horizontal which minimizes the vertical bounce. Wow- mind blown
I’ve always loved the aesthetics of these videos, the choice of background, lighting, even the part colors, you obviously put a lot of effort and attention to all these. Lovely blend of pleasant footage, informative builds and a perfect amount of humor, all very lovely. Keep it up!
Really enjoyed! i do think through that the stiffness of the chassis, number of wheels, wheelbase and the hight of the load bed, had a large role in some of the models loosing its peaces. Would also bee cool to see an air suspention version!
The crawl voyager and the summit seeker I feel were the most stable designs here, as both barely lost their loads during the treadmill test. Really good concepts!
I have seen many of your videos, but have you done already torsion bar? there were different types done over history specially on military vehicles, but I have not seen them done at a "lego scale". What about a version of the summit seeker ones but with magnets instead of springs. Almost any version that uses springs could be replaced by magnets, or double magnet suspension to make it smoother. Anyway, great job as usual.
4:40 FINALLY LEAF SPRING SOLID AXLE SUSPENSION! Wanted to have one for sooo long… Edit: i remade the rubber cruiser’s axles, made steering, but I’m missing 30 rubber connectors…
Enthusiastically, I really like the Crawl Voyager, Rubber Cruiser and Bounce Nomad because they carry heavy things. They’re also good at carrying more passengers than the others.
The Summit Seeker really has a very creative suspension system that works really well, I could definitely see this being used in cars. P.S. You do a great job with your vids, keep up the good work!
What a fun video! Great work. Would be cool to see a version where wheelbase, wheel type, and the location of the center of gravity of the load are the same across models.
Polarity Pathfinder was innovative, but Rubber Cruiser the simplest solution. Try front-rear interconnected (like Citroen 2CV or Rover Metro) to make pitch frequency much lower. Then try some of the interconnected methods used on NASA Pathfinder and Spirit/Opportunity rovers.
these videos are the epitome of an architects dream, the fact that most of the vehicles are unstable merely adds onto that fact, the treadmill is extremely wasteful of pieces as you could have used 2 sprockets exclusively and had a liftarm link them together, as a person who has a scarce amount of lego pieces and enjoys making rc cars, i am extremely disappointed as people who are more fortunate and have a wider array of parts for building mechanisms like this are not only terrible at making those mechanisms but also just cannot take a quick break on how to build certain things.
Thanks for breaking down the suspension types and their timestamps! That’s a really helpful overview for anyone following along. If you have any more insights or suggestions, feel free to share!
Dr. Engine, I found great pleasure in this video. Thank you for maintaining a consistent posting schedule. As a result, I have become a new subscriber. Does anyone else share my sentiment?
Hi! Dr. Engine. I'm DDadan, a Korean Lego youtuber. Your experiment with Lego is really amazing and interesting. Would it be okay if I made a video introducing your Lego experiment to Korean Lego fans? Of course, I'll leave the source!
I really like the leaf spring design with the rubber technic bushings, but my favourite is definitely the pushrod setup at the end. I haven't really seen that type made from Technic.
Very impressive, I think that the Crawler Voyager is very promising. However I would've liked to see a suspension geometry based on the Citroen 2 CV or if possible the most advanced hydropneumatic from later models
I absolutely love watching these videos! This one was super fun especially! Really interesting to see how each of these builds manages the challenge at hands.
In almost all of these challenges, a much softer spring rate would have provided a better result. Perhaps a test combining several suspension types together? I also feel that a similar wheel base would lead to better results
As a suspension engineer i've watched it with my kid accidentaly, and now im watching all your vids. Would be lovely to use some rc car shocks with actual damping ;)
à 1:34 et 9:17 the idea seems to be to have a low car with many wheels with a global equilibrium between the wheels, and, to cancel the vibration of the car, i eard somewhere that some car use pistons with oils to equilibrate.
The summit seaker has by far the best results, but after some use, the rubber bands might have an easy time snapping. For reliability and maximum preformance i would go with the rubber cruiser. Further testing and reliability enhancements to the seaker might make it the obvious choice.
There's a lot going on here! I noticed the...cab mounted suspensions, Where the wheels themselves were on a separate platform behaved worse than a solid axle. I think if you combined independent 6 or 8 wheel suspension with a dampened version of the bounce rover you wouldn't lose much at all. On the chain suspension If the chains were light duty elastic and secured from the top and bottom of the mounting posts to the corners of the cab like an x split in two it might retain more, could try on the sides too instead of just the front. No matter which design retains more product it will either be the most complicated to assemble and work on or expensive to build and maintain which is why your Amazon boxes show up dented and you can hear the delivery truck hit bumps from 8 blocks away.
I liked the performance of the Crawl Voyager the most. It seemed the smoothest in most tests. A good all-rounder. It was also kind of mesmerizing to watch.
I believe it is not fair comparison, as you are changjng the full joints mechanism and build when you change the suspension types, my recommendation to use and joint construction for all which will allow you totake accurate performance for each. My point is each suspension type will have the same joint support setup with that you can ignore any other factors which will affect the suspension performance
Crawl voyager: Reliable and nice for sustained travel. Also would probably be perfect for smaller tests as one wheel not touching the ground at a time is no problem. The summit seeker is the best in all the tests, but might not be better for average challenges. Then again, you might want to climb up some stuff and it is Lego, so you are facing scaled up objects. So, I guess that means Summit Seeker wins

I like how the chain shaker performed better after it destroyed itself
Yeaa
it was so funny
but also bcs he build it with the center point to high up
basic idea behind sports cars
It has just proven how faulty (or even nonexisting) the test methodology was.
That rubber cruiser is like a leaf spring setup, that’s cool.
and it also has some degree of damping, just like a leaf spring! :D
Definitely my favorite one
mine too!@@yackson4804
My favorite one aswell!
@DrEngine And it makes me wonder if it would perform worse or better if the wheels were not connected with axle
I don't know for how much realism you want to go, but it would be more accurate and scientific if all the wheelbases would be the same.
Yea I felt the summit seeker had a bit of an advantage as a result if a larger wheelbase
+ center of gravity! Some were really tall
The loads also need to have the same moment arm from the wheels! ... not that I'm here for realism ofc 😂
Same amount of wheels as well.
Also ground clearance on some gave advantage on some tests.
0:35 swing axle suspension
1:31 swing axle suspension
4:31 solid axle suspension

@@nathanielscholtens2812 rohan was correct, it is a pushrod suspension.
Thanks for the pin @DrEngine
I was really impressed by the summit seeker. It took a vertical vector and absorbed the energy by converting it horizontally
Same way a lot of modern race car suspension is designed.

In a lego recreation of the rb16 Red Bull car I made that form of suspension! The shocks run parallel to the chassis of the car.
My mind is blown. My Lego cars are forever changed. I need to rebuild all of them with these amazing suspensions.
just don't use the chains

@@coreyduma325 It's useful data if you look at the entire vehicle and not just the suspension.
Someone’s ripping off your vids on tik tok btw

He's been termed

The crawl voyager fared well in all tests. Looks compliant and steady .
The only one that did a little bit bad was the drop test, the rest was really steady
It was the number of wheels, more stability with a lot of give per wheel.
@@iftekimas9260 probably because it had really soft suspension it bottomed out too quickly

A suspended cart design can be great to keep a load level, but not like this.
A big advantage of magnets though in this case is they're really small so can be used in combination with other methods. For example using soft shock absorbers, and adding magnets to make the suspension progressively stiffer.
The chain should connect to the top of the basket, not the bottom. That's a big part of why it tipped so much.

It's actually a very similar setup to what Formula 1 cars use.
it's similar to some mountain bike suspension designs

I think it's based off of a real thing, look up "double wishbone suspension"
Thanks for the credit! Cool testing setup, I would have expected my suspensions to do worse :)
Thanks for the ideas!
My favorite is the magnet suspension system, in my opinion it was just ingenious
I'd love to see a video in which you try and optimize the perfect suspension in an evolution style progression. Great video ❤️
Great suggestion! Thank you for watching!
Ingenious - I mean, the mechanisms are quite simple, but building a working machines like this just from LEGO, just wow.
Thank you for watching! Glad you like it!
tomorrow i have my exam and im watching 9 types of lego suspention

Yea, that drastically changes the result even if the same suspensions are used. Great video but IMO he should have tried to keep it similar.

That is why chain suspension isn't used on motorized vehicles.
That front bar keeps it from catching air. Pretty cool but not quite there.

all suspension solutions are based on stiffness and the stiffness solution lacks elements that will dampen vibrations, i.e. a vibration damper

😋
Rubber will typically results in a better ride due to its natural dampening effect, spring based cruisers had too much rebound wity no dampening.
Playing LEGO... still one of the best ways to spend your time🤩
suggestion: put all of the suspensions ontop of eachother and see if it really is the smoothest
Nice idea💡
When I saw you building the Summit Seeker I knew, this one’s gonna be the best

You know a good thing to use in this situation is a gyroscope which always wants to be at the same place it started
This is just amazing. great video
Loved the summit seeker, because you used pushrod suspension and it reminded me of Formula 1. This suspension is really impressive
Appreciate the F1 comparison. Pushrod suspension is tricky.
Can we please get a behind-the-scenes look at the Lego suspension testing facility? I need to see this magic in action.
i have no words... this is just amazing
What an amazing piece of work you've done here! Very inventive and well thought out!
I think it was a clever way to control for variance by using different wheels and tires for every test

The chain shaker took the word "suspension" a bit too seriously.
9:03 German car suspension be like
(Complex, expensive, and always broken but effective)
WHAT OH you're a genius
I believe it is not fair comparison, as you are changjng the full joints mechanism and build when you change the suspension types, my recommendation to use and joint construction for all which will allow you totake accurate performance for each. My point is each suspension type will have the same joint support setup with that you can ignore any other factors which will affect the suspension performance
This is very impressive!
If the spring rover has a more solid rubber band i think then it can make a pretty good suspension
You could try to create just one car with the diferent suspensions combined
In the end everything depends on the angle of the car when it falls, This depends a lot on the method of dropping the car
You should make a tank with the Crawl Voyager suspension system!
I think the solid axle leaf spring design wins it here
Nice video
The rubber cruiser dances like a hiphop car 😂
