【摘要】 军用密封电磁继电器是广泛应用于运载火箭、导弹、卫星等武器装备系统与航天系统中的关键元器件,工作环境的复杂性要求其必须具备良好的耐力学性能。本文应用 MSC．Patran软件建立了密封电磁继电器整机有限元模型,完成了模态分析过程与谐响应分析过程,分析验证了整机结构的传振路径。通过分析结构中关键位置的振动加速度响应曲线及触头接触力的响应曲线,确定了安装耳固定的最佳位置。同时分析了整机重心位置对触头接触性能的影响,所得结论对于军用密封电磁继电器的抗振性能的提高具有实用价值。更多还原

【Abstract】 Hermetically sealed electromagnetic relay in military, as a kind of important electronic components in the field of aerospace and weapon system is widely used in high reliability and performance requiring devices like rockets, missiles, satellites. In this paper a finite element model of hermetically sealed electromagnetic relay is built, through normal modes analysis and frequency response analysis, the vibration transitive path is studied. The result curves of acceleration response and force response of the finite model which indicate how the position of the mounting ear and central gravity affect the relay’s anti-vibration character is investigated. In the end, the best position of mounting ear is found and the relation between relay’s structure and performance of anti-vibration is analyzed. The conclusion of this paper is of great value for the hermetically sealed electromagnetic relay manufacture and optimizing.更多还原
