Hi,

is it possible to give a solid a defined eigenfrequenzy. The Problem is i had to do a modal Analysis of a satellite structure and the first eigenmode had to be above 40Hz, but my tank had a eigenmode at 30Hz. But i know that the frequqnzy of the real tank is 45Hz. So can i give the solid a eigenfrequency with 45Hz?

Thanks for your help

    Hi @hubéry10

     

    You can change the frequency by changing mass, material etc... 

     

    You can also do optimization (topology optimization, shape optimization) to change the frequency.
