Abstract

The rectangular plate vibration has been of immense interests to the researchers for a long time. In this literature, an investigation is performed to measure the dynamic response at the different points on a rectangular plate due to excitation at different points. The possibility of occurring different modes of vibration at the different points on the plate according to the position of excitation is demonstrated and explained from the modal shape of the plate obtained from the modal analysis. A conventional approach is performed to obtain the modes and the modes are compared with the FEM results. An analytical equation is used to obtain the dynamic deflection of harmonic excitation for free vibration to observe the occurring of different modes and also used to validate the results obtained from the finite element method. Then a constant damping condition is simulated to understand properly the variation of amplitude at different points of plate for different excitation conditions.
