In ISO4210 the horizontal front load is described with a mass that is falling from a specific height on the front axle of the bicycle but not as a force. How did you come up with the 2x1000N of force acting on the axle?
Is it possible to consider 1) a composite frame, with a discrete ply/laminate definition (based on classical laminate theory), and 2) transient impact analysis based on an initial velocity (such as the ISO4210 physical test definition)?
If I put two cilindrical constraints at the rear of the chain stay and a vertical support on the front tube, and apply a vertical downward force at the sit, should I expect the front tube to displace away from the sit or to come closer? My geometry is very similar to yours, a classical safety diamond shaped frame
if I have two valid results after running fea analysis where both do not cross the yield strength then how to choose the right answer and why to chose that particular answer
@26.29 with the lower position Seat stay - you can see more stress in the Seat tube compared to traditional design high mounted seat stay connected at seal collar . i think the newer Design is Retarded and just MARKETING BS to sell more bikes to the MINIONS !!!!!!!!!!! No Added Beneft + a HARSHER RIDE !!!!!!!!!!! Since the SEAT STAYS are SHORTER
Can you pls explain what are boundary conditions for braking and irregularities?

Is there any standards or codes to design and concept the bikes according to that codes? standards dimensions and all details please ????
Why do you use a 3d mesh instead of a 2d with less elements?
You could but we only offer 3D elements at the moment. We already saved some time by using half the model though as you have seen :)
Playback speed 1.75. works good
Braking what is the load calculated
