A TRANSIENT SIMULATION RESEARCH FOR THE CHARGING OF SPACECRAFT IN THE WORST CHARGING CASE
-
摘要: 运用等效电路模式理论推导出随时间变化充电问题的微分方程组,针对最严重情况构造了解决瞬态充电问题的程序。对ATS-6卫星的二种情况运用这个程序进行了计算。讨论了航天器不同材料对充放电的影响。Abstract: In this paper,a set of differential equations for the transient charging of spacecraft is deduced by the equivalent circuit model,then,the computer program under the worst charging conditions is made.With this program,the charging of ATS-6 is calculated in the two conditions respectively.Finally,the effects of different materials of spacecrafts on charging and discharging are discussed.
