MCNP模拟卫星深层充电特征

MCNP Simulate the Internal Dielectric Charging Process of Satellites

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.

charging, charging. Aiming at the operating faults of geosynchronous orbit satellite due to medium^s internal we put forward Monte Carlo method to simulate the process of the medium~ s internal 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.
