飞机结构表面涂层与机体结构零件之间的热膨胀系数的失配引起的残余应力影响着涂层的机械和物理性能。使用拓扑优化方法设计涂层和零件之间适当的界面形式,使整个结构的总应变能达到最小。优化结果可为不同尺寸零件的涂层设计提供参考。 Residual stresses caused by the mismatch of thermal expansion coefficients between the aircraft’s structural surface coating and the structural parts of the aircraft affect the mechanical and physical properties of the coating. The topology optimization method is used to design the appropriate interface between the coating and the part to minimize the total strain energy of the entire structure. The results of the optimization can provide reference for the coating design of different size parts.
