摘要
为真实模拟月尘与物体表面吸附作用,地面模拟试验时需使模拟月尘带电。基于电选矿、静电除尘给颗粒物加电的技术,提出一种等效方法,通过电晕放电使模拟月尘带电;设计并搭建了电晕装置,测试了装置电晕放电性能;使用装置研究了电晕电压对加电电荷量的影响以及湿度对电荷保持时间的影响。结果表明:该电晕装置可实现模拟月尘加电;电晕放电电压越高月尘电荷量越大,环境湿度越小电荷衰减时间越长。
To simulate the adhesion effect of the lunar dust to solid surface,the electric charged dust was supposed to be simulated during ground effect test.Based on the technology of power dressing and electrostatic precipitator,a method of corona discharge was proposed for charging the lunar dust simulant.A corona device was set up and the performance of the device was tested.With the corona device,both the effect of corona charge voltage on charge quantity and the effect of humidity on lasting time of being charged were tested.The results showed that the corona device could be applied to the charging of lunar dust simulant.Higher corona initial induced voltage resulted in higher electric charge,while lower humidity led to slower decay process.
