Hi
I am using OptiStruct.
I am doing an analysis on rotor part of an alternator. I considered the parts of interest (two parts with slide contact) without shaft. I generally use RFORCE for simulating centrifugal forces under constant rotation.
But in this case, I want to simulate the case where the RPM varies with time. I am doing nonlinear direct transient analysis by applying varying RPM by TLOAD1 (RFORCE is selected as EXCITED, TABLED1 is selected at TID).
My case involves contact non linearity. and i want to apply time varying RPM (RFORCE). Is there any other way out doing this?
Is it possible to do this in nonlinear static analysis rather than going to nonlinear Transient analysis?
