中文摘要：

航天用电磁继电器“高可靠、宇航级”目标的实现，与提高其耐力学环境能力密切相关。本文基于有限元软件MSC．Patran／Nastran，通过对某航天用电磁继电器振动特性的仿真计算，完成了安装方式因素对继电器抗振性能的影响分析。

英文摘要：

The development goal of electromagnetic relay is “high reliability and aerospace grade level”, which has closed relationship with the anti-mechanical environment ability. The 3-D solid model of relay was built by using commercial FEM software MSC. Patran/Nastran, therefore the effect of installation style was investigated by modal analysis and harmonic response analysis.
