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 mechanismis used for carrying out vibration loading on a tested Mars rover and comprises a first vibration platform, a vibration loading assembly and a second vibration platform which are sequentially arranged from top to bottom, the first vibration platform is used for being arranged at the bottom of a wheel of the tested Mars rover, the vibration loading assembly is arranged between the first vibration platform and the second vibration platform, and the vibration loading assembly is connected with the second vibration platform. Compared with the prior art, the amplitude and frequency of the wheels are adjusted through the eccentric distance adjusting structure, single-degree-of-freedom vibration loading of the tested Mars rover within the range of 0-10 Hz is achieved, the mechanismis simple, testingis accurate, and precision is high.

    本发明提供一种火星车移动系统振动加载机构及性能测试装置,属于火星探测测试设备技术领域,所述火星车移动系统振动加载机构,用于对被测火星车进行振动加载,包括从上到下依次设置的第一振动平台、振动加载组件和第二振动平台,且所述第一振动平台用于设置于所述被测火星车的车轮的底部,所述振动加载组件设置于所述第一振动平台和所述第二振动平台之间,且所述振动加载组件与所述第二振动平台相连接。与现有技术比较,本发明通过偏心距调节结构调节车轮的振幅与频率,对被测火星车实现在0‑10Hz范围内单自由度振动加载,结构简单,测试准确、精度高。
