摘要:

针对卫星介质深层充电诱发地球同步轨道卫星运行故障, 提出一种Monte Carlo方法模拟介质深层充电过程.  将航天器介质平板充电过程简化为电子穿过屏蔽层进入介质环氧树脂.  通过MCNP软件, 模拟不同屏蔽层铝的厚度及不同能量电子对卫星介质内最大电场的影响.

关键词: 深层充电, MCNP软件, 电子

Abstract:

Aiming at the operating faults of geosynchronous orbit satellite due to medium’s internal charging, we put forward Monte Carlo method to simulate the process of the medium’s internal charging. The  plate model charging process of  spacecraft medium is simplified as  electron  crossing the screen of  aluminium into epoxy.  With the help of  the MCNP software, we obtained the results that different thicknesses of aluminium and different electron energies influence on the largest electric field of medium.

Key words:  internal charging, MCNP software, electron
