Hello

In SolidWorks, is it possible to perform motion analysis on a block connected to a spring and damper that have non linear properties containing mathematical functions like signum, step, etc?

Like this?-->

Fd= c*v^2* sign(v)

Fs= k*x^2* sign(x)

Where Fd is damper force, Fs is spring force

c is damping constant

k is stiffness of spring

sign is the signum function.

Please let me know how to put custom mathematical function of a spring in the motion simulation.

Thank you very much.

This would be so much easier in MATLAB Simulink. OK, try adding a force and use expression
