摘　　要：本文分析参数激励下简支矩形屈曲薄板非线性振动特性及分叉行为。讨论板的几何参数、激励参数对分叉行为的影响。用Ｍａｎｉｋｏｖ法分析全局分叉。This paper analyaizes nonlinear viberation performances and bifurcation behaviour in hingedsquare plates subject to parametrical excitations.The effects about geometric parameters of the plate and excitative parameters on bifurcation behaviour have been disscussed.The global bifurcations of the plate are analysized by way of manikov.
