| The paper mainly introduces environment factors on Mars, which affects the spacecraft work. These environment factors include low atmospheric pressure, large temperature change, CO2 atmospheric, high wind speed, dust storm, etc. Firstly, these environment simulation methods are set forth, including pumping and charging gas method for the low pressure environment simulation (the low pressure range is 150~1500 Pa), gas exchange method for the CO2 environment simulation (the volume fraction of CO2 is 95%), gas nitrogen temperature adjustment method for the large temperature environment simulation (the temperature range is –150~150 ℃), vacuum diversion simulation method and low-pressure wind tunnel simulation method for dust storm environment (0~100 μm diameter of Martian dust), scenario simulation method for topographic landscape (coarse and medium sandy landscape), solar simulator simulation method for irradiated environment, and the lamp array method for the radiation environment simulation (the highest radiance is 1760 W/m2), counter weights method for the low gravity simulation (the gravity is 3.72 m/s2). Secondly, two types of integrated environment factors simulation methods are set forth, including Mars low pressure and thermal test, Mars wind tunnel. |
