Abstract

Finite difference simulation of a flexible rectangular plate structure is an investigation which presented about the dynamic characterization of a two dimensional flexible plate structure. To control the vibration of the plate efficiently, it is required to obtain an accurate model of the rectangular plate structures. An accurate model will lead to the realization of satisfactory controL Therefore, a thin, flat rectangular aluminum plate, with all edges clamped, is considered. Simulation algorithm which characterizing the dynamic behavior of the plates is developed through a descretisation of the governing partial different equation formulation of the plate by using finite difference method and implemented within Matlab. It will allow application and sensing of a disturbance signal at any mesh point on the plate. Such a provision is desirable for the design and development of active vibration control technique. The performance of the developed algorithm in characterizing the dynamic behavior of the system is assed in comparison to previous result reported by various methods. The algorithm validation will be presented in both, time and frequency domain. That the measured parameter associated with the first three resonance modes of the system compare with the previous result which has been reported. Thus, the simulation algorithm developed and validated forms a suitable test and verification platform in subsequent investigations for development of active vibration control strategies for flexible rectangular plate structures.
