摘要
操纵支座是机尾翼后缘部段一个承力和传力的关键元件,主要作用是为操纵面作动器提供固定支持,并将作动器的作动载荷传递给机尾翼盒段。作为承受集中高强度载荷的零件,应满足强度和耐疲劳等要求,同时追求轻重量目标。基于SIMP插值拓扑优化模型,以结构总柔顺度最小化为优化目标,运用Inspire软件对操纵支座结构进行拓扑优化,获取操纵支座最佳结构形式和截面参数,并通过有限元分析,结果表明操纵支座满足静强度和疲劳强度要求,结构实现减重约40%。
The actuator fitting is a key element of bearing and transferring force in trailing edge of wing and stabilizers, whose main effect is to provide fixed support for control surface actuators, and transfer the dynamic load of actuators to the wing and tail box;therefore, the actuator fitting should satisfy the requirement of high strength and fatigue resistance, as well as low weight. Based on Solid Isotropic Material with Penalization (SIMP), the topology optimization of actuator fittings is carried out through Inspire software for the purpose of minimizing total compliance of the structure. The results of finite element analysis show that the operating support meets the requirements of static strength and fatigue strength. And the optimal result shows that the weight is reduced by about 40% under the premise of satisfying the strength and functional requirements.
