Abstract
The paper describes an experimental study of Clamped, Simply-supported, Clamped, and Simply-supported (CSCS) elastic thin rectangular plates subject to a large amplitudes forced vibration. Our goal is to determine the amplitude-frequency dependence. For this end, a test rig was designed and made, on which an electrodynamic exciter located at the center of the plate provides the transverse harmonic excitation whereas an accelerometer measure the vibration amplitudes generated. The experimental data will compared to numerical result obtained and published by Z. Beidouri et al. We have also demonstrate the feasibility of the Benamar’s method, already experimentally validated in fully clamped rectangular plates made by different materials, in the CSCS boundary conditions case.
