Abstract

The invention discloses a lunar surface environment flying dust simulation measurement test bed device which comprises a lunar surface environment simulation mechanism, a measurement system, wheels and a wheel movement mechanism. The lunar surface environment simulation mechanism comprises a rack, a vacuum cover, simulated lunar soil, a soil tank and a vacuum pump. The soil tank is fixed in the vacuum cover, the simulated lunar soil is uniformly laid in the soil tank, the rack is fixed above the soil tank, and the vacuum pump is communicated with the interior of the vacuum cover through a pipeline. The measuring system is installed in the vacuum cover and used for measuring flying dust particle parameters and wheel parameters. The wheel movement mechanism comprises a horizontal sliding mechanism, a lifting mechanism and a wheel transmission mechanism. The horizontal sliding mechanism is installed on the rack and can horizontally slide above the soil tank, the lifting mechanism is vertically connected to the lower portion of the horizontal sliding mechanism, and the transmission mechanism is installed at the bottom of the lifting mechanism, connected with the wheels and used for driving the wheels to rotate on the surface of simulated lunar soil. The test bed is suitable for flying dust measurement of wheels under different loads and different specifications.

Description

technical field [0001] The invention belongs to the technical field of lunar dust suppression, and in particular relates to a test bench for simulating the dust raising in the lunar environment. Background technique [0002] The surface of the moon is covered with a thick layer of lunar soil. The lunar soil is composed of particles with an average particle size of 75 μm. When the manned lunar rover drives fast on the lunar soil, the particle size of the lunar dust is less than 20 μm. Under vacuum conditions, it is difficult to remove. All astronauts who have reached the surface of the moon have found that the troubles caused by moon dust are far beyond imagination. These particles will not only pose a threat to the health of astronauts and cause damage to spacesuits, but also the moon dust attached to various surfaces of the spacecraft will cause many failures, posing a great threat to the reliability and safety of the space system. [0003] The wheel dust phenomenon caused...
