Optimization of plate vibro-isolation from the acoustic point of view

Dupal J.

Modelling and Optimization of Physical Systems

2008

z. 7

19--22

The paper deals with a methodology of vibro-isolating foam distribution under plate modeled by FEM. A special finite element with viscous-elastic foundation containing a cavity was developed. The characteristic proportions of the cavities are used as the optimization parameters for minimization of surface velocities of the plate. The weighted sum of velocity amplitudes over the frequency broad band can be taken into account as a criterial function of optimization process.
