Hi Wenlong,


thanks for your help


1) I am not sure to understand the meaning of rigid body motion as all the components in my analysis are deformable


2) I was not sure about how to run an analysis with rigid bodies, instead I have created a material called "rigid" with a young's modulus of 2E+20Pa


3) I have run the modal analysis but I am not sure about what to conclude of it


 


here is another screenshot with the boudaries conditions.


In A it is a remote displacement, everything is fixed but the rotation arround the x axis (which is free).


In B it is a remote displacement, everything is fixed but the rotation arroud the x axis and the translation along the z axis (which are free).


this way, the front fork is able to move and rotate as it would be on a bicycle in the real world.


the brown component (the frame) is flexible and the gree/blue ones are flexible with a high Young's modulus.
