Dynamic response analysis of a thin rectangular plate of varying thickness to a traveling inertial load

In this article, a new generalization of the orthonormal polynomial series expansion method is introduced as a robust computational approach to assess the transverse vibration of a 2-D distributed parameter system. A thin rectangular plate of non-uniform thickness is considered, for which the natural frequencies and dynamic response to a lumped moving mass are computed. Verification is presented via analytical solution and excellent agreement is achieved. Some benchmark solutions are obtained for the dynamics of non-uniform plates under moving loads. Also, the similarity of the presented solution with eigenfunction expansion method in the contribution of the mode shapes is underlined.
