摘　　要：本文导出了一般粘弹性厚板含剪切、挤压和转动惯性效应的动力方程,它是弹性厚板动力方程的推广.据此方程还可退化得到若干种类型的中厚度粘弹性板的动力方程.In this paper an equation of motion is presented for a general thick viscoelas-tic plate, including the effects of shear deformation, extrusion deformation and rotatory inertia. This equation is the generalization of equations of motion for the corresponding thick elastic plate, and it can be degenerated into several types of equations for various special cases.
