摘　　要：针对传统接头分解器体积大、效率低且反复使用后容易损坏的问题,本文基于均一化方法,建立多目标的拓扑优化数学模型,以刚度和固有频率为目标,体积和应力为约束,对分解器进行拓扑优化设计。优化前后有限元分析结果表明,分解器减重10%,最大位移降低23.9%,最大应力降低37.2%,结构安全系数大于1.15,固有频率显著提升,保证了结构良好的抗振性能,实现钢轨绝缘接头分解器的轻量化设计,为钢轨绝缘接头分解器结构设计提供技术支撑。Aiming at the problems of large volume,low efficiency and easy damage after repeated use of the traditional joint resolver,this paper establishes a multi-objective topology optimization mathematical model based on the homogenization method.The topology optimization design of the resolver is carried out with the stiffness and natural frequency as targets and the volume and stress as constraints.The finite element analysis results before and after optimization show that:The weight of the resolver is reduced by 10%,the maximum displacement is reduced by 23.9%,the maximum stress is reduced by 37.2%,the structural safety factor is greater than 1.15,and the natural frequency is also significantly increased,which ensures the good vibration resistance of the structure,realizes the lightweight design of the rail insulated joint resolver,and provides theoretical basis and technical support for the structural design of the rail-insulated joint disintegrator.
