摘　　要：使用热刚度计算理论,进行了不同温度场和不同结构材料的热颤振特性研究.通过热应力分析理论,获得结构在不同温度场作用下的热模态,应用Van Dyke活塞理论计算高超声速非定常气动力,采用p-k法进行颤振求解.通过对相同结构形式、不同温度场和不同材料的翼面结构进行热颤振特性对比,得出热应力对结构的影响.The thermal flutter characteristics of structure in different temperature and different material are researched using the thermal stiffness analysis method. First, through the thermal stress analysis, the thermal frequency in different temperature is got. Then, using Van Dyke piston method, the hypersonic unsteady aero is calculated. The flutter equation is solved by P-K method. Through thermal flutter analysis to the same structure in different temperature and using different material, the influence of the thermal stress to the structure is obtained.
