Noise and vibration analysis software

[427591HJ]

Hi

I would like to know which are most expended softwares for analysis noise and vibration. I use ProENGINEER for modeling. Could anybody recommend me any software for analysis noise and vibration.
Thanks

What is your application? If you are interested in machinery condition monitoring, take a look at:

My application is noise and vibration of Power Transformers

Your question is very general and just a little vague: are you looking for software to perform analysis on experimental data, or software to do simulations?

If the former, I can strongly recommend Head Acoustics' Artemis software for acoustic analysis, with vibration analysis being just a bit more cumbersome; or LMS' software for acoustics and vibration.

I would guess that since you have mentioned noise and vibration analysis and ProEngineer, you are attempting to analyse the response of a "virtual" model based on your solid model. It is possible to tranfer Pro geometry to virtually any pre processor or desktop FEA pakage.

Depending on the depth and specifics of your analysis, you may need to solve an FEA normal modes model (my recomendation is NEiNastran). The results of the normal modes analysis can be fed to an acoustic package (FEM or BEM)and used to solve a coupled analysis (my recomendatio is VNoise). This means that your analysis would characterize both interior and exterior sound fields, taking into account both airborn and structure born paths. If you are interested in high frequency noise, then you would be best served to use a statistical energy analysis package (SEAM or AUTOSEA). High frequency can only be defined by the specifics of your actual geometry, as it is based on the modal density.

If your geometry is simple, most FEA and acoustic packages offer some rudimentary geometry creation tools that you could use to approximate the problem.

If you don't need both interior and exterior results, you may be able to avoid the need for modal information.

You can obtain an perpetual NEiNastran for around 10k, and perpetual VNoise for about 9k. SEA usually costs about 20k annually.

Hope it helps.
