THE NONLINEAR VIBRATIONBIFURCATION OF INCLINED BEAMUNDER THERMAL STATE

摘要

摘要: 利用Ｇａｌｅｒｋｉｎ原理及Ｍｅｌｎｉｋｏｖ函数法研究了斜梁在热状态下的非线性振动分岔，并讨论分析了温度、长高比、倾斜角对斜梁发生混沌运动区域的影响．

Abstract: The nonlinear vibration bifurcation ofinclined beam under thermal state is studied byGalerkin principle and Melnikov function,and theeffects of temperature, ratio of length and width,inclined angle to area of chaotic motion occurringin inclined beam are discussed.
