Vibration Response Problem

Vibration Response Problem

Vibration Response Problem

(OP)
Hi
I am a new user to ansys. I want to calculate the vibration response of a simple supported beam. I used the transient dynamic analysis  and POST1 for the calculation of strain of all the elements
i used ETABLE command to calculate the strain
i want to calculate the strain for different values of the load. however, i get the same strain values for every load case.
can you please help me to get the correct solution

RE: Vibration Response Problem

Hi,
Maybe you should try spectrum analysis, which is usually used for vibration analysis.

RE: Vibration Response Problem

If you are in a transient analasys, you will need to use Post26.  Post1 will just return results from the last substep.
