Abstract

The invention provides a Mars rover moving system vibration loading mechanism and a performance testing device and belongs to the technical field of Mars detection testing equipment. The mechanismcomprises a first vibration platform, a cam structure and a second vibration platform which are sequentially arranged from top to bottom, the first vibration platform is connected with the cam structure,the first vibration platform is further connected with the second vibration platform through an elastic structure, and the first vibration platform is arranged at the bottom of a wheel of the tested Mars rover. Compared with the prior art, performance testing is completed through a cam structure with the variable eccentric distance, the amplitude and frequency of wheels are adjusted, single-degree-of-freedom vibration loading of thetested Mars rover within the range of 0-10 Hz is achieved, the structure is simple, testing is accurate, and precision is high.

Description

technical field [0001] The invention relates to the technical field of Mars exploration and testing equipment, in particular to a vibration loading mechanism and a performance testing device 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 performance test of the Mars rover mobile system on the ground is an important part of the design and experimental verification stage of the Mars rover, and the performance test process of the Mars rover mobile system on the ground includes simulating the vibration of the wheels of the Mars rover on different terrains, However, the vibration l...
