建立一套可行的气动热、气动力、结构松耦合数值方法,利用商业软件ABAQUS二次开发接口DFLUX,编制热壁热流计算程序以考虑壁面温度的影响,分析舵面结构在气动加热环境中温度场分布及随飞行时间的变化;建立力热模型分析舵面模态和频率随气动加热的变化情况;应用商业软件ZAERO进行颤振分析,确定舵面气动弹性稳定性及颤振发生机理.%A numeric method of the coupling of aerodynamic heating, aerodynamic force, structure was built, and the interface DFLUX of the software ABAQUS was used to program the hot-wall heat flux calculation procedure for considering the wall temperature. The temperature distribution and the changes with the flying time of rudder structure were analyzed. Established the thermal-mechanical model to analyze the rudder modal and the changes of frequency as aerodynamic heating was changing. Finally, the commercial software ZAERO was used to analyze the flutter to identify aeroelastic stability and the flutter principle of the rudder.
