采用有限元方法研究复合材料层合板结构在线性温度场作用下非线性热振动特性．采用特征值屈曲分析方法，判断了结构在线性温度场作用下的临界屈曲分歧点，计算了结构的一阶弯曲固有频率，分析了铺层角度及铺层层数对结构临界屈曲温度分布和结构固有频率的影响，总结了其对复合材料层合板结构热振动特性影响的一般规律．这些结论对复合材料结构设计、抗热设计有一定的指导意义．
By using the Finite Element Method (FEM)，the nonlinear thermal vibration characteristics of composite laminated plates under linear temperature field were investigated. Based on the eigenvalue buckling analysis method, the bifurcation point of an ideal linear elastic structure was estimated. And the critical buckling temperature distribution and the lowest nature frequencies of composite laminated plates with different layers and orientations were also calculated and analyzed. Moreover, the general regularities of temperature effect on the thermal vibration characteristic of the composite plate structure were summarized. All these conclusions will give guidance on structure design and heatresistant design.
