Frequency Response Analysis in I-DEAS 1

[toothroot]

Hi all,

Is it possible to perform a frequency response analysis of a FE-model in I-DEAS? If so what steps need to be performed?

Thanks in advance,
Daniel

Hai daniel,

What is the input and output?

1) Do you need displacement or velocity or acceleration response?

2) Are you interested to solve using mode superposition method or full method or reduced method?

Yes, It is possible to carry out the frequency response analysis.

One better example is there in verfication manual. If you unable to trace out, e-mail me, I will e-mail you the path in help.

Hi elogesh,

The part I'm trying to analyse is a boring rod (Input: force on tool center point, output: displacement response spectrum). It is more or less a beam with some incisions and additional features. I'm trying to use mode superposition (as it is done in the response analysis tutorial). I've found the NAFEMS test case you've mentioned (thanks for this hint!), but the universal file containig the model doesn't work because I can't pick any costrained DOF's. The I-DEAS help is more than poor on this topic.

Regards,
Daniel
