矩形板的非线性热振动分岔

THE NONLINEAR THERMAL VIBRATION BIFURCATION OF RECTANGULAR PLATE

用Ｍｅｌｎｉｋｏｖ－Ｈｏｌｍ ｅｓ 法研究了矩形板非线性热振动的分岔，并讨论分析了温度、长宽比、厚度等因素对矩形板可能发生混沌运动临界条件的影响。

By using Melnikov Holmes method, the nonlinear thermal vibration bifurcation of rectangular plate is discussed, and the effects of temperature, length to width ratio, thickness etc. to critical conditions of chaotic motion possibly occurred in rectangular plate are investigated.
