摘　　要：给出了一种把具有波纹型夹心的正交各向异性夹层板的控制方程组化为仅包含一个位移函数的单一方程的简单方法 。A simple approach to reduce the governing equations for orthotropic corrugated_core sandwich plates to a single equation containing only one displacement function is presented, and the exact solution of the natural frequencies for rectangular corrugated_core sandwich plates with all edges simply_supported is obtained. Furthermore, two special cases of practical interests are discussed in details.
