| 摘 要： | 根据等效电路理论模式,通过计算机模拟了航天器在强亚暴空间环境下阴暗区和光照区两种不同环境下的表面充电情况。选取了比较有代表性的充电情况的等效元进行分析,并参照了ATS-6卫星的实际数据。结果表明,考虑到数值模拟中各种近似条件的假设,模拟结果和实际充电情况基本符合。

| Abstract: | According to the equivalent circuit theory,a simulation of the spacecraft charging is conducted in this paper on the conditions of eclipse and sunlight at a worst magnetic substorm time. An analysis on six representative equivalent units of charging is compared with the measurement of ATS-6 satellite. It is shown that the simulation results agree with the test data in the same conditions. |
