Integral environment experiment system of Mars detector product

Abstract

The invention discloses an integral environment experiment system of a Mars detector product. The integral environment experiment system is an experiment system for simulating a gas atmosphere-air pressure-temperature integral environment on a surface of the Mars and mainly comprises a vacuum chamber, a high- and low-temperature chamber, a temperature control system and a pressure control system,the setting of the integral environment under a Mars environment is achieved by the high- and low-temperature chamber, the temperature control system and the pressure control system, and the environmental temperature condition of the Mars detector product in the vacuum chamber is achieved. The integral environment experiment system is simple in structure and is convenient to install and debug, theproblems of heat leakage and tank wall moisture condensation caused by direct experiment of a vacuum tank are effectively solved, the risk of CO2 crystallization caused by heat leakage is reasonablyprevented, and the temperature control efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of comprehensive environmental tests of spacecraft, in particular, the invention relates to a comprehensive environmental test system for carrying out ground simulation tests for Mars probe products. Background technique [0002] Similar to Earth, Mars also has an atmosphere that is mainly composed of CO 2 , the surface air pressure is 500Pa-1400Pa. In winter, the polar region enters eternal night, and the low temperature makes as much as 25% of CO in the atmosphere 2 It precipitates into dry ice in the polar regions and sublimes into the atmosphere again in summer. This process causes the air pressure around the polar regions to change repeatedly throughout the year. Therefore, the Mars rover model products need to work in a relatively harsh air pressure-temperature comprehensive environment, and have extremely high reliability requirements. It is necessary to carry out comprehensive environmental test ve...

AI Technical Summary

Problems solved by technology

The current thermal vacuum test equipment, one is that the ambient temperature is uncontrollable, and the internal temperature of the tank is too low to maintain CO 2 The gaseous state; another kind of ambient temperature can not meet the test temperature requirements (-105 ℃), can not match the test requirements of the Mars model

In order to meet this kind of test requirements and avoid insufficient assessment of the Mars rover during the test process and the failure to fully expose product design and manufacturing defects, it is very necessary to develop a comprehensive environment that can truly and accurately simulate the "gas atmosphere-pressure-temperature" of the surface of Mars test system
