Moon surface dust environment simulating method and simulating device

Abstract

The invention discloses a moon surface dust environment simulating method and a simulating device. The moon surface dust environment simulating method includes a first step of vacuumizing the atmosphere in a cavity through vacuum equipment and enabling the vacuum degree to approximate the moon surface environment, a second step of enabling dust samples to be placed in a sample groove in the cavity, adjusting temperatures of the dust samples within the range of minus 190-150 DEG C, and using a microporous film to seal the dust samples in the sample groove, a third step of carrying out ultraviolet irradiation on the dust samples through deep ultraviolet spectrum, and enabling the dust samples to be electrified through external photoelectric effect, and a fourth step of enabling the dust samples to float through electric field attraction, creating the dust environment, controlling environmental temperatures by means of a quartz lamp array, and controlling dust density and motion intensity through adjustment of ray intensity and electric field intensity so as to achieve the purpose of simulating the cosmic dust environment. The moon surface dust environment simulating method and the simulating device solve the problem that the actual moon surface dust environment can not be effectively simulated in the prior art. The moon surface dust environment simulating method is easy to implement, and the simulating device is simple in structure and good in using effect.

Description

Technical field [0001] The invention relates to the field of machinery, in particular to a method and device for simulating the dust environment of a moon surface. Background technique [0002] The external environment faced by a spacecraft performing a lunar exploration mission and a spacecraft orbiting the earth is very different. According to the flight records of the Apollo era, one of the most notable points is that the lunar soil and moon dust have a significant effect on the reliability of the spacecraft. Posed an extremely severe challenge. In order to ensure the smooth implementation of the Apollo moon landing plan, the United States conducted research on the causes, environmental effects, and ground simulation methods of the lunar soil and lunar dust environment in the 1950s and 1960s. In recent years, with the "return to the moon" viewpoint, research in this area has once again become the focus of attention. [0003] After the realization of the manned space mission, C...

Problems solved by technology

However, there is usually electrostatic migration of lunar dust on the illuminated surface of the lunar surface, which causes the lunar surface to be wrapped in a large amount of floating moon dust; especially near the junction of the morning and evening lines, the electrostatic migration of lunar dust is more intense, and lunar landing equipment must face this. harsh environment

The current simulation of the lunar watch second environment is not realistic enough
