Abstract
This report presents a numerical method to investigate the frequency response of a rectangular plate. When we use the transfer matrix method to calculate frequency response of plates, exciting force is limited to a line force and applicable object is also restricted. For this reason, we propose a method to calculate modal parameters from free vibration analysis by using the transfer matrix method. Modal mass are calculated by numerical integration from modal vectors. We have applied this method to calculate the frequency response of plates. Comparing the results obtained from the proposed method and finite element method, characteristics of the frequency response have a good agreement with each other.
