摘要
在某地球静止轨道通信卫星平台布局的基础上,通过合理地简化和假设建立了南蓄电池舱作为热分析计算模型,对影响蓄电池在轨温度波动的机理进行分析。分析结果表明:在冬至,西板、对地+Y板和背地+Y板受照外热流的日变化会引起其内表面温度大幅度波动,通过舱内热辐射又会引起服务舱南板等结构板内表面温度波动,而服务舱南板通过导热将引起安装其上的蓄电池温度波动,这是导致蓄电池温度波动的根本原因。
Based on the layout of the GEO communications satellites bus,the thermal math model（TMM） of south satellite battery cabin was presented to analyze the mathematical mechanism that influences battery temperature on orbit.It is shown that daily change of orbit heat flux will obviously influences the temperatures of west board,＋Y panel of Earth deck and ＋Y panel of anti-Earth deck,and further influences the temperature of service module（SM） structure board through radiation,which induces the battery temperate variation through SM board conduction.This is the key reason of battery temperature variation.
