BAJA/SAE engine support

Hello,I'm simulating the engine support for my team's BAJA/SAE.

I have coupled static structural, modal and random vibration simulation. However, I had never used random vibration before and wanted to know if I am doing it wright.

We know that the engine will have a maximum vibration of 85 Hz, so in my PSD displacement tabular data I used frequency values between 1 and 85 Hz, for the displacement I used my stactic structural maximum deformation. Is this the wright way to do it ?

Ps: I tryed using my modal data in the psd, but those vibrations are between 200 and 650 Hz, driving to some bad results.

English is not my first language, please excuse any mistakes.
