Abstract

The invention provides an environmental simulation method and system capable of achieving a low dew point in a large normal-pressure space. The environmental simulation method capable of achieving the low dew point in the large normal-pressure space is provided through comprehensive use of a liquid nitrogen storage tank, a water bath vaporizer, a gas storage tank, a circulating fan, a heater, a test chamber and the like. The purpose that a coated piece is protected through a large space solid lubricating coating structure and a mechanism product in a thermal test is achieved.

Description

technical field [0001] The invention relates to an environment simulation test technology for aerospace, in particular to an environment simulation method and system capable of realizing a low dew point in a large space under normal pressure. Background technique [0002] Space environment simulation test is an important means to test and ensure the reliability of space vehicles and other equipment. With the continuous development of aerospace technology, according to future development needs, large-scale high-power spacecraft require thousands to tens of kilowatts of power, and small and medium-sized rigid solar cell arrays are no longer suitable for these occasions. battery array. Focusing on the urgent need for high-power energy systems and large-scale antennas in future space stations, large-scale early warning satellites, and large-scale earth observation satellites, the experimental verification technology of large-area ultra-light solar cell arrays and large-scale hi...
