摘要
本文应用传递矩阵法研究了变截面圆拱的自由振动。用解析法推导了等截面圆拱单元的精确传递矩阵 ,再应用传递矩阵原理建立变截面圆拱自由振动的特征方程。该法具有计算简单、节约内存的优点 ,可方便地用于实际结构计算和设计。
In the paper,the free vibration of circular arches with variable cross_section is studied by transfer matrix method.Applying analytical method,the exact transfer matrix of circular arches with constant cross_section is derived.The characteristic equation for the free vibration of circular arches with variable cross_section is established by use of transfer matrix method.The method presented in the paper has advantages of simplicity in calculation and of save in internal storage and can be conveniently used in the calculation and design of practical structures.
