torsional spring design

Please login with a confirmed email address before reporting spam

I'm trying to calculate the spring constant for different torsional spring designs. I can apply edge loads (forces) to one end of the spring, and simulate the displacement, but would like to be able to apply a displacement and calculate the reaction force or torque to the displacement. Can anyone point me in the right direction or suggest tips? I'm relatively new at COMSOL and would appreciate any help!

Thanks.

Felix

Hi

there are different ways in 3.5 and 4 where the Rigid Connector BC has appeared but note that the latter make your boundary stiff. See also the moment load in the 3.5a structural doc. There are several threads already about this subject, try a search on the forum
