Noise reduction
Hi Bradh, Thanks for your input, it was very helpful, Regarding the forced frequency response analysis, could you please put some more light on it. I have done frequency response analysis in nastran before but I don't know for this problem, what would be the load value I need to apply (should...- laxman

Vibration Fatigue Analysis using MSC-Fatigue
I have a problem involving transient response of a system where the frequency of the input sinusoidal load changes every 0.22 seconds and the amplitude is maintained at a constant peak. I have a frequency v/s stress data from frequency response analysis. I also have a ascii file of time v/s load...- laxman

Noise reduction
Hi, I have a small dc motor, which fits into a enclosure. As soon as the running dc motor is fitted into the enclosure (press fit), the motor noise gets vastly amplified. This needs to eliminated. Can anyone suggest me some tips to handle this problem in the FEA point of view!. Thanks Laxman- laxman
