Mars rover moving system traction performance testdevice

Abstract

The invention provides a Mars rover moving system traction performance test device, andbelongs to the technical field of Mars detection test equipment. The test device comprises a support base for supporting a tested Mars rover; aresistance moment loading mechanism which is used for being connected with wheels of the tested Mars rover and loading resistance moment to the wheels of the tested Marsrover; a traction loading mechanism which is used for being connected with a body of a tested Mars rover and applying traction force to thetested Mars rover in the walking process of the Mars rover; and a vacuum tank and temperature control mechanism which is used for containing the tested Mars rover and controlling the control vacuum degree and temperature of the test environment. The resistancemomentloading mechanism and the traction force loading mechanism are both arranged in the vacuum tank and temperature control mechanism. Compared with the prior art, the performance test of the Mars rover moving system on the ground can be realized, the wheel load and the wheel resistance moment required by different geomorphic characteristics can be simulated, and the requirements of 0-3000N traction force loading technical indexes and loading precision can be met.

Description

technical field [0001] The invention relates to the technical field of Mars exploration and testing equipment, in particular to a device for testing the traction performance of a Mars rover moving system. Background technique [0002] my country's Mars exploration is in full swing, but because Mars is farther away from the earth and the environment is more complex, the exploration of Mars is more difficult and risky. Therefore, it is necessary to conduct a large number of test experiments on the ground to conduct comprehensive checks and tests on the Mars rover to ensure the reliability of the Mars rover. [0003] The traction performance of the rover's mobile system is the main factor affecting whether the rover can complete its mission in the space environment. Therefore, the performance test of the rover's mobile system on the ground is an important part of the rover's design and experimental verification stage. The performance test of the system mainly includes traction...

Problems solved by technology

[0003] The traction performance of the rover's mobile system is the main factor affecting whether the rover can complete its mission in the space environment. Therefore, the performance test of the rover's mobile system on the ground is an important part of the rover's design and experimental verification stage. The performance test of the system mainly includes traction performance test, vacuum environment fatigue resistance characteristics, etc., but there is no performance test equipment on the ground for the Mars rover mobile system in the prior art
