星用材料静电放电信号分析

ESD SIGNAL ANALYSIS OF SPACECRAFT EXTERIOR SURFACE MATERIALS

地球同步轨道卫星的在轨故障分析表明,ESD(静电放电)是导致卫星故障的重要原因之一,它约占故障总数的30%左右。文章叙述了ESD 信号的定量分析方法并报导了若干星用材料的充电和放电特性,其中包括Ag-SiO_2微晶玻璃、S-853白漆、SB-3消光黑漆、阳极化铝等材料。

According to the statistic analysis of geosynchronous space-craft abnormal events,the ESD(electricity static discharge)is one ofthe primary causes,It possessed about 30%,of the total abnormal events.This paper describes the method of quantity analysis of the ESD signaland reports the charging and discharging characteristics,of a numberof spacecraft exterior surface materials included Ag-SiO_2 micromeriticglass,S-853 white paint,SB-3 darken paint,anodizing aluminum and soon.
