Small-sized comprehensive simulation system of lunar environment

Abstract

The invention discloses a small-sized comprehensive simulation system of lunar environment, which mainly comprises a vacuum system, a heat circulating system, a lunar dust simulating system, a radiation environment simulating system and a monitoring system. By adopting the vacuum system, the problem that a vacuum pump is damaged by a lunar dust simulated article in the vacuum-pumping and vacuum-keeping process is solved and the service life of the vacuum system is prolonged; and by adopting the lunar dust simulation system, the simulation problem of a lunar dust environment on a lunar surfaceis solved. The system integrates simulation abilities of multiple environment factors like high and low temperature circulation, lunar dust, vacuum ultraviolet, electronic radiation and the like in one vacuum chamber, and can be used for carrying out a simulation test on a single factor and comprehensive simulation test on the multiple factors. By using the invention, comprehensiveness and reliability of a lunar environment simulation test are increased and efficiency of a space environment simulation test also can be improved.

Description

technical field [0001] The invention relates to a lunar environment simulation test system, which belongs to the testing field. Background technique [0002] The moon is 3.8×10 from the earth 5 km, its orbital environment is very different from that of the earth's orbital environment. The solar radiation constant in lunar orbit is 1399W / m 2 , since there is almost no atmosphere on the surface of the moon (pressure below 10 -10 Pa), so the temperature difference between day and night on the surface of the moon is very large, the daytime temperature is 403K ~ 423K, the shadow area that the sun cannot shine and the temperature of the moon surface during night is 93K ~ 113K. The maximum temperature difference on the surface of the moon is 330K. The temperature of the solar panel of the lunar polar orbit satellite is 180K~360K [1，2] . On the surface of the moon, the lunar probe must also withstand the radiation environment of electrons, ultraviolet rays, and protons, as wel...

AI Technical Summary

Problems solved by technology

[0004] ① The results of a single environmental factor test are not enough to reflect the effect of complex environmental factors on the moon, and the results of simple superposition also cannot reflect the effect of comprehensive effects, that is, a single environmental test cannot replace a comprehensive environmental test;

[0005] ②The test accuracy is not high, and the same sample needs to be exposed to the ground atmospheric environment during the conversion process of different environmental simulation tests, which will affect the test results;

[0006] ③The test efficiency is low, each sample needs to go through multiple simulation tests, wasting a lot of test time
