Thank you for the informative article. What does the damping look like if I want to damp an axial vibration. I'll be specific: in a model airplane there is an internal combustion engine in the head. This generates a vibration in the axis from front to back. How can I dampen the vibration, for example in the middle of the airplane? I want to place a flight controller there and avoid exposing it to maximum acceleration.
Man i love this ! So simple looking yet so much thought behind it, this is good engineering
How about using three circular wire ropes (two small, one larger) instead of springs?
A lot of those things don't make sense to me. There is a negative transmissibility but that is into a number that can be negative. It seems to me like they just created a low frequency isolator.
lovely
They may post wrong result....I tried simulation I got the same result as they showed, mass is not moving after 6 hz..but before it is amplifying
This is work that is 60 years old. Still interesting.
very nice work!!
This is AMAZING. I wonder if it coud be extrapolated to metal sheets, knowing they behave similar to paper. Any insight in that? Also i think you coud pull a 2 hour video about this subject easily, and i would watch it. Glad i found this video, thanks! (i'm from argentina, bad english sorry)
This is inspiring. What an exciting field this is. I am not an engineering student. I'm a psych grad student yet my keen interest in this field stems from my trying to solve a movement/vibration problem on a 6DOF sim racing motion platform (my new sober hobby - there will be a RUclips channel) for which has both actuator movement and haptic vibration that needs to be isolated. I'm going to reach out to some people in the academic world and hope they might be able to advise me! So, expect to hear from me, Professor.

很前沿的研究，应用前景无限
Dear sir , i am considering doing your wonderful experiment as my Major project in final year B tech, can you please explain how to carry on the experiment for taking the reading for plotting the graph.
cool cool cool
Great video and presentation. How can I get this product? Or the specs to print my own? Because our site needs this to stabilize wall mounted cameras and nothing else works adequately.
Brilliant work
Hellow thanks for the interesting video, I wonder why there still hava a viverations? i think the zero stiffness can remove all of vivrations
Amazing Work!
nice job! is the code of the energy analysis available?
Fascinating work and an excellent presentation, too. Thank you.
This video introduced me to the interesting word of quazi-zero stiffness systems :)
I have a question regarding the horizontal shaking test. Wouldn't the random shakings from the two shakers cancel out yielding a smaller effective shaking?
No, if they're un-correlated then you'd expect the resulting vibration to have a magnitude larger by a factor of the square root of 2. Sometimes they cancel, sometimes they combine, but overall its an increase in vibration.
@@Kruglord You are right. I think the sqrt(2) factor is for Gaussian noise though, for uniform random the factor is more like 1.33 (at least that's what i find numerically)
Hello sir, that phenomenal work. I would want to know isin't this a compliant mechanism ? And would you say that the origami's tendency for these behaviour is dependent on the shape of curvature and it's extrusion thickness ?. Thank you for your time.
Congrats on your great work. I wonder how you solved the equation of motion in the y-direction, Equation S16, to find the isolation results in the frequency domain, please. I mean whether you used Simulink since it is a nonlinear function or any other method.
Very interesting experiments!!! But, could you tell me some differences between conventional QZS mechanisms and yours? If you do so, then the originality of your research will get much stronger.
