Using rolling constraint rather than ground contact model for CMC?
Posted: Mon May 08, 2023 9:09 am
Hello All!
Is it possible to use a rolling constraint during CMC rather than a ground contact model? If so, what is the best way to add that to the model? I've been using a HuntCrossley based GCM and it seems to be producing pretty good vertical GRFs, but the ML and AP GRFs still seem pretty far off regardless of what friction and stiffness parameters I use. I'm open to any suggestions y'all might have to produce better GRFs from CMC.
Thank you in advance!
