根据我国某载人航天器在轨飞行时的空间环境和航天器表面带电的机理，对航天器表面带电进行了仿真，并对结构切割地磁场的感应电势进行计算。在此基础上，分析了表面带电对航天员出舱的影响，以及出舱安全性防护措施，计算出主动电位控制系统最大发射电流。研究结果可为航天员出舱安全防护提供参考。

Based on the space environment of manned spacecraft, this paper analyzes the surface charging mechanism. Simulations are conducted to calculate the charging potential as the structure passes through the earth magnet field, to reveal the influence of the surface charging on astronaut extravehicular activities. Some security protecting measures are proposed for the extravehicular activities(EVA). The active potential control approach is proposed to solve the high transmitter current and provide a design guidance for the EVA safety.
