Vibration Analysis of Rectangular Plate by Finite Strip-Transfer Matrix Method

本文提出一种弹性矩形薄板振动特性分析的新方法，该方法是把结构振动特性分析的传递矩阵法与有限条法相结合，使得联立方程阶数大大降低。此方法不仅可以节省内存，而且可以利用条元的重复性提高计算效率。精度与有限条法相同，且适合实际应用。

This paper presents a new method for analyzing vibrational characteristics of elastic rectangular thin plate. By combining the transfer matrix method of vibration characteristics analysis of structure and the finite strip method, the order of the matrix is greatly reduced. This algorithm can not only save the storage space, but also utilize the duplication property of the strip, thus it improves the computational efficiency and gives results of high accuracy. The method is suitable for application in engineering practice.
