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.

    本发明提供一种火星车移动系统牵引性能测试装置,属于火星探测测试设备技术领域,包括支撑基座,用于支撑被测火星车;阻力矩加载机构,用于与被测火星车的车轮相连接,对被测火星车的车轮进行阻力矩的加载;牵引力加载机构,用于与被测火星车的车体相连接,在火星车行走过程中对被测火星车施加牵引力,以及真空罐及温度控制机构,用于容纳被测火星车并控制测试环境的控制真空度和温度,且阻力矩加载机构和牵引力加载机构均设置于真空罐及温度控制机构的内部。与现有技术比较,本发明能够实现火星车移动系统在地面的性能测试,模拟车轮负载与不同地貌特征所需的车轮阻力矩,能够满足0‑3000N的牵引力加载技术指标和加载精度要求。
