In-Plane Free Vibration Analysis of a Annular Plate with Intermediate Supports

In this paper, the authors formulated analytical algorithm for the in-plane free vibration of a annular plate with intermediate support part by the transfer influence coefficient method (TICM) which is based on the successive transmission of influence coefficients on nodal circumferences. To confirm the effectiveness of the suggested algorithm, we analyzed the free vibration of a annular plate with three typical intermediate support parts by the TICM and the Transfer matrix method (TMM) on a personal computer. The computational result was that the TICM was superior to the TMM in the in-plane free vibration analysis of a annular plate with rigid intermediate supports.
