810 Dynamic response analysis of non-circular cylindrical shell structures based on the transfer matrix method

Abstract

This report presents a numerical method to investigate the frequency response of shell structures. Transfer matrix method is a useful approach to analyze the vibration problem of continuous systems because of its computational efficiency. However, when we use the transfer matrix method to calculate frequency response of the shell structure, exciting force is limited to a line force and applicable object is also restricted. For this reason, we use a method to calculate modal parameters from free vibration analysis by using the transfer matrix method. We have applied this method to the frequency response of shell structure. Comparing the results obtained from this method and ANSYS, characteristics of both frequency response have a good agreement.
