| 摘 要： | 采用Ｇａｌｅｒｋｉｎ原理研究复合材料单层板热状态下的非线性振动分岔，利用Ｍｅｌｎｉｋｏｖ函数给出了复合材料，单层板热状态下受横向微扰时发生混沌运动的临界条件，并得到了温度升高、长宽比增大使混沌运动区域变大，板厚增加使混沌运动区域变小的结论。

| Abstract: | The nonlinear vibration bifurcation of composite material lamina under thermal condition is studied by using Galerkin's principle.The critical conditions that chaotic motion of composite material lamina under thermal condition may possibly occur during forced vibration are discussed by using Melnikov's funation,and it comes to the conclusions that chaotic motion district increases with the rising of temperature and the increasing of length to width ratio and decreases with the increasing of board thickness. |
