摘要
本文采用数值方法对圆锥壳在余弦载荷作用下的动力屈曲问题进行了探讨。利用非线性几何方程建立了锥壳的基本动力屈曲方程。采用级数展开和伽辽金法等方法对方程进行了简化,使之成为常微分方程。方程的求解则采用龙格库塔法,最后给出临界冲击载荷值。
A study was made to determine the dynamic with impulsive cosine load.Methods of solution include linear differential equations are solved by a program of stability of the truncated thin circular conical shell the Fourier series and Galerkin procedure.The nonRunge-Kutta integration.
