Freq. Res. Direct (displacement ) response

Pinkal Fichadiya

We are trying to simulate Vibration test of Battery pack. In that, load step is of frequency response (direct).My load is RLOAD2 (excitation id is of accln load 2g). I want to post-process acceleration, displacement, phase response at certain frequencies .How can we do that?

Hi,

 

have you tried looking at the tutorials?

You can setup the FRF and request the GLOBAL_OUTPUT_REQUEST for disp, accel, vel, etc, in formats such as .punch file, defining magnitude/phase, and post-process these into HyperGraph.

Depending on your model size, you might want to consider modal FRF as well for computational cost saving.
