Abstract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。
Other AbstractDust removal by means of an electric curtain is analyzed theoretically and demonstrated experimentally. A critical "floating" voltage criterion is introduced, above which the effect of the Vander Waals force on dust movement can be overcome. The relationship between critical voltage and frequency of the alternating field is derived. The results of numerical simulation as well as experiments show that the dependence of critical voltage on frequency is different for low and high frequencies. For high frequencies critical voltage is in direct proportion with frequency, while in low frequencies there is a lower limit of critical voltage. The experiment result coincides with our simulation conclusion. This method to remove dust does not abrade the circuit boards and has promising applications in the future exploration of deep space.
