Hi,
I'm trying to simulate a brake disc undergoing constant force braking. I need to see how stresses change as the pad moves around the disc or vice versa.
Whats the best way to do this? Is there anyway if i model the pads shape to apply a force on the pad area and have that force move around the disc at a certain rpm?
Thanks

Hi Stephen,
Using MES with Nonlinear Material Modesl and surface contact can help simulate this. To make the model simple, we can do like this:
(1) Schech the model in which the force on the pad pointing to the center of disc along z- direction
(2) Fix x- and y- tranlation of the pad
(3) apply a force on the pad along z -direction. Use a load curve to settle the force first before the disc rotates.
(4) for disc, add joint using beam element to roate it. Fix the nodes in the center of joint.
