摘要
本文用双向三角级数法求解矩形夹层板和中厚度板自由振动微分方程,给出其解析解,可以求解四边为任意边界条件的矩形夹层板和中厚度板的固有频率。
In this paper the differential equations for the free vibration of rectangular sandwich plates and rectangular plates of moderate thickness is solved by the method of two-direction trigonometric series.Its analyti- cal solution is given.It can be used to solve the free vibration frequency of the rectangular plates with arbitrary boundary.
