某星载阵面电源分配器随机振动及冲击分析

Random Vibration and Impact Analysis of Space-Borne Array Power Supply Distributor

星载阵面电源分配器的作用是将试验舱内的储能电池、平台母线提供的电源进行汇流并分配至各个功能模块,其可靠性至关重要。通过有限元法对阵面电源分配器进行随机振动及冲击分析,根据分析结果校核阵面电源分配器的刚度及强度,结果表明结构设计满足星载环境使用要求。

The function of the space-borne array power supply distributor is to concentrate the power of the storage battery and the platform bus in the lab module and distribute it to each function module.Its reliability is crucial.In this paper,the random vibration analysis and impact analysis of the array power supply distributor are carried out by means of the finite element method.Through the analysis results,check the structural strength of the array power supply distributor.The results show that the structure design meets the operational requirements of space-borne environment.
