Abstract
A unique shield system of lunar dust has been developed utilizing electrostatic force to remove dust breaking into bearings and mechanical seals of equipment used for lunar exploration. A single-phase rectangular voltage is applied to parallel plate electrodes printed on substrates at the gap of the mechanical sealing part. Approximately 60% of dust was repelled from the gap, and it was predicted by the numerical calculation using the distinct element method that the cleaning performance of the system would be further improved in the low-gravity and vacuum environment of the Moon. This technology is expected to increase the reliability of equipment used in long-term manned and unmanned activities on the lunar surface.
