摘要
应用一般解析解求解混合边界条件矩形板的振动问题。一般解析解是一种能用于求解板各个边和各个角为任意边界条件的振动问题。首先将板分成若干部分,使每一部分仅为均匀的边界,每一部分的若干边为独立的可用边界条件确定。同时另外的若干边为与另一部分的边相连,则由连续性条件确定。由板的全部边界条件和连续性条件建立的方程式即可用于求解自然频率和振型。以板边一部分为简支,另一部分为平夹或自由为例进行计算,并与其他文献进行比较。
The general analytical solution may be sued to solve the vibration problem of rectangular plates with mixed boundary conditions.A general analytical solution is a solution which can be used to solve the vibration problems of plates with arbitrary boundary conditions of all edges and all corners.Firstly,divide the plate into several parts to make each part with uniform edges.For each part some edges which are independent can be determined by boundary conditions.While some edges which are connected with other...
