摘　　要：对质量检测器结构进行有限元分析(FEA),针对分析结果进行结构设计优化,对优化后结构通过仿真分析和力学试验进行方案验证。结果表明:FEA方法可以准确分析出质量检测器的结构特性,对质量检测器结构设计能否满足航天力学环境适应性给出指导性结论;锁紧螺母端增加定位环可以大幅降低锁紧螺母在随机激励作用下的振动响应,明显提升对随机振动的力学适应性。The finite element analysis(FEA)of the structure of mass detector is carried out, and the structural design optimization is carried out according to the analysis results.The optimized structure is verified by simulation analysis and mechanical experiment.The results show that the FEA method can accurately analyze the structural characteristics of the mass detector, and give a guiding conclusion on whether the structural design of the mass detector can meet the aerospace mechanical environment adaptability.Adding a positioning ring at the end of locking nut can greatly reduce the vibration response of the lock nut under random excitation, and significantly improve the mechanical adaptability to random vibration.Through simulation analysis and mechanical experiments.
