摘　　要：感应式磁力仪传感器安装于卫星舱外伸杆末端,为了避免在卫星发射过程中由于承受着严峻的力学载荷冲击而导致损坏,传感器结构需具备优异的力学性能。针对感应式磁力仪传感器的结构设计,基于SQP算法,结合有限元仿真分析和动力学灵敏度分析,以传感器刚度、强度、一阶模态频率等作为性能约束条件,以传感器质量作为目标函数,建立优化问题数学模型,不断优化传感器结构设计参数直至满足指标要求,这对实际工程应用中类似结构的优化设计问题具有一定的参考意义。In order to protect the induction magnetometer sensor fixed on the end of a deployable boom of the satellite from the severe mechanical environment during the launching process,the induction magnetometer sensor should have sufficient stiffness and strength in structure.In this article,we combine finite element analysis and sensitivity analysis to establish a proper optimization model,making the stiffness,the strength and the first modal frequency of the sensor as the constraint conditions,the mass as the objective function.Based on the sequential quadratic programming algorithm,we resolve the problem until we get an optimal solution.The structural optimization of the induction magnetometer sensor can provide reference and basis for the structural optimization of other similar equipment.
