Lunar dust grains threaten the safety of lunar lander and astronauts, because of adhesion. In order to reduce their threat, electrostatic adhesion mechanism and adhesive mechanics model of lunar dust are studied by using Discrete Element Method, Finite Element Method and Image Method in this paper. An electrostatic adhesive mechanics model is derived with electrostatic field theory and verified based...
In order to reduce the destruction of lunar dust electrostatic adhesion on detector and related equipment, technology of particle removal and charging model are researched. The technology of photoelectric dedusting is proposed. According to the particle orbit theory, current of photoelectron and electron are respectively obtained. Based on Maxwell energy distribution, the density distribution function...
In this paper, an initiative charged particles cleaning research based on PLZT was developed to solve performance degradation and other issues of optics which were caused by surface adhesion between charged particles and optics. Firstly, a constitutive model of particles based on discrete element theory was established because of characteristics of charged particles such as small size and being charged,...
