Hi Guys,

 

I am simulating random vibration in optistruct. I have input psd in (m/s^2)/Hz, model content in mm, output required is stress in MPa. I submitted 1 run and  i am getting high stress which are not realistic. Unit excitation is 9810 (SPCD) and I have submitted another run with unit excitation 1 (SPCD), here i am getting very low stress which is not realistic. Can anyone suggest me the right procedure. I guess i have mistake in unit conversion. If anyone having dummy procedure file please share me.

 

Thanks all in advance

looking forward to get some input from experienced analyst.

    It's really hard to say if you did not upload a model to show how you build the model.
