摘要: 文章论述了某卫星三向力限FMD振动夹具的设计方法，并运用有限元方法分析了其频率和受力情况。通过两种力传感器分布方式的对比给出了优化设计方案。最后针对螺钉进行了校核，给出了选型依据。

Abstract: This paper discusses the design of the vibration fixture for satellite three-directional FMD, and analyzes its frequency and stress by using the finite element method. An optimized design scheme is obtained by comparing the distribution modes of two force sensors and a check on the strength of bolts.
