电帘除尘被认为是最有可能在深空探测中应用的除尘方法之一.利用电动力学基本理论分析了平行电极清除颗粒的条件,引入克服范德瓦尔斯力对颗粒运动影响的临界悬浮电压判据,并获得了该除尘临界电压与交流电频率之间的关系.理论计算和实验结果表明,在频率较低和较高的情况下,临界电压取决于不同的物理机制. The electric curtain dust removal is considered as one of the most suitable dedusting methods for deep space exploration.According to the basic theory of electrodynamics, the conditions of the parallel electrodes for removing particles are introduced, and the critical levitation voltage, which overcomes the influence of van der Waals forces on particle motion, Criterion and get the relationship between the critical voltage and AC frequency.The theoretical calculation and experimental results show that the threshold voltage depends on different physical mechanisms at lower and higher frequencies.
