Embodiment Construction

[0021] The content of the present invention will be further elucidated below through specific embodiments. Of course, the following specific embodiments are described only to illustrate different aspects of the present invention, and should not be construed as limiting the scope of the present invention.

[0022] First of all, the dust test system for simulating moon dust of the present invention will be constructed, such as figure 1 As shown, the moon dust flying dust test system of the present invention includes a vacuum container 1, a rotary test bench 2, a shaft assembly 3, a wheel 4, and simulated moon dust 5. The interior of the rotary test bench 2 is laid with simulated moon dust with a height greater than 10 cm. 5. The rotating shaft assembly 3 is composed of the rotating shaft and the wheel shaft connected to it in a cross rotation, and is fixedly connected to the bottom of the rotating test bench through the rotating shaft. The wheel 4 is connected to the wheel shaft...

Abstract

The invention discloses a testing method for simulating lunar-dust dust rising. According to the testing method, a wheel is rotatably connected with a wheel axle and can rotate around the wheel axle; meanwhile, the wheel and the wheel axle are rotated around a rotary shaft; in a testing process, a rotary test bed and the rotary shaft are rotated synchronously; the wheel is in tight contact with the simulated lunar dust and a test is carried out in a vacuum container; finally, a dust rising height of each time of testing is determined by utilizing a ruler and a particle image tachymeter to measure and collect dust rising image data. When the test is carried out, a lunar-dust dust rising phenomenon is not generated when the wheel is rotated to achieve a certain rotary speed; the lunar-dust dust rising phenomenon is intense along the increasing of the rotary speed of the wheel. According to the method, the lunar-dust dust rising phenomenon caused by rotating the wheel is firstly simulated under the vacuum environment and the image data of the dust rising height is measured and collected by the particle image tachymeter.

Description

technical field [0001] The invention relates to the technical field of space environment effect simulation test methods, in particular, the invention relates to a test method for simulating moon dust. Background technique [0002] At present, all astronauts who have reached the surface of the moon can find that moon dust poses a great threat to the reliability of spacecraft systems. For example, during the landing of the probe, the driving of the rover, and the walking of the astronauts, the phenomenon of moon dust will be generated. Very adverse effects, and even affect the efficiency of the solar array. Therefore, the moon dust simulation test is very important in spacecraft reliability research, but because the real moon dust material on the ground is very precious, the test needs to be carried out by simulating moon dust instead of real moon dust. [0003] Based on this, the present invention proposes a dust raising test method for simulating moon dust, which is mainly...
