屈曲黏弹性矩形板的非线性振动分岔

摘要

采用Melnikov法及Galerkin原理研究了屈曲黏弹性矩形板的非线性振动分岔，并讨论分析了长宽比、板厚等因素对屈曲黏弹性矩形板发生混沌运动区域的影响.%The nonlinear thermal vibrationbifurcation of bucking viscoelasticrectangular plate is studied by Melnikov's method andGalerkin's principle, and the effects of ratioof length and width, thickness of plate etc.to buckling viscoelastic rectangular plate withchaotic motion field are discussed.
