we need to give vibrations as input. so for that wat kind of physics we need to apply and wat are the procedures to proceed the input process.

Hi

what kind of "vibrations" you can either simulate in the time domain (tedious and long, but required in some cases, i.e. random testing time evolution ... or easier via the frequency sweep method. If you have a PSD of the vibration spectra you can use this method, wich coresponds to the harmonic development of the solution.

But not all physics nor all models are adapted, it all depends ;)

Good luck
