驻波电帘除尘效率的实验研究

摘要

月尘将对在月球表面进行巡视探测的设备产生严重不利影响。文章分析了利用驻波电帘对探测器的太阳电池板进行尘埃清除和防护，给出了电帘表面的电场分布，颗粒在电帘表面的受力状态和起跳、跃移过程，通过实验测量给出了电帘结构各参数对除尘效率的影响，制备了自清洁演示系统，对电帘的能耗进行了测定；表明驻波电帘是月表探测任务中尘埃防护的有效方法。%Lunar dust is expected to pose great harm to the instruments for lunar surface explora- tion. In this paper, dust removal from solar panel by using standing wave electric curtain is stud- ied. The electric field distribution on surface of the curtain is revealed, forces and levitation and transportation processes of the dust particles are investigated. Through experimental measure- ment, the influence of the structural parameters of electric curtain on the dust removal efficiency is characterised. A selbclean solar panel demonstration system is manufactured, and the energy consumption of the electric curtain measured. The results convey that electric curtain is an effec- tive technology for dust control in lunar surface exploration mission.
