My system is made of two bracket support (like are used in air conditioning), one shelf and a vibrating motor. I am going to plug the engine and to measure the vibrations (the response in the frequency ...) in the table. I am sorry if my English is not very good. Thank you very much.
Hi,
unless you have non-linearities (but it doesn't seem so...), then harmonic response should be what you need. I'd suggest to carefully read the Ansys help on this topic, it is very well done.
