Reply To: PSD (random vibration) and Acceleration on a body (harmonic response)

[AR]

 

Hi,

I have managed to apply the acceleration to the motor in the Harmonic Response analysis. I leave the process below for other users who have this question:

You have to declare the CMACEL in the modal. You have to apply it to a body, a volume, previously defined as a Named Selection (in my case BODY1). The Named Selection has to be created before solving any of the analyses so that it is passed to the Solver!!

After applying the CMACEL in the Modal, in the Harmonic Response I declare the LVSCALE to apply the scale to the CMACEL that I have applied before. In my case it was 1, but you can declare the CMACEL as 1 and in the LVSCALE with the corresponding value. The SFDELE is to eliminate any residual force that may have been applied.

Regarding the application of the acceleration to the motor for the Random Vibration, I have not achieved anything. Could you help me?

Regards
