中文摘要:

用于探月工程对接机构地面对接性能试验的对接性能测试台（性能台），其运动模拟器的惯量值会影响地面试验数据的准确性，由于性能台运动模拟器质量、惯量需与飞行器完全一致，因此对惯量开展原位校准测量具有重要的现实意义。首先基于附加质量配重的弹簧振子法建立了运动模拟器的运动振动方程和转动惯量原位校准方法；其次基于SimMechanics软件工具箱搭建了运动模拟器附加质量配重前后的运动模型并仿真出两个模型的振动周期，根据理论模型和仿真出的振动周期计算出仿真惯量，验证了理论算法的正确性；最后，基于音圈电机和限位机构组建校准装置对运动模拟器进行原位校准试验以及试验的主要误差来源分析。实验结果表明，3个轴的惯量校准结果与理论值的偏差均不大于5%，装置引起的测量误差小于2.5%，小于运动模拟器最大允许误差的1/4，该校准装置能够解决性能台运动模拟器惯量校准的难题。

英文摘要:

The inertia value of the motion simulator of the docking performance testing platform (‘performance testing platform’ for short), applied for docking mechanism ground docking performance tests used in Lunar Exploration Program, can affect the accuracy of ground test data. As the inertia of the motion simulators for the performance test-bed must be exactly the same as those of the spacecrafts which the test-bed simulated, there is the great practical significance to measure the inertia of the motion simulators in-situ. In this paper, the motion vibration equation and in-situ calibration method of rotational inertia for the motion simulators is firstly investigated based on the additional mass spring oscillator method. Secondly, the mechanism motion models of the motion simulators are built based on SimMechanics Tollbox Software before and after attaching additional counterweights, the vibration periods of the two models are simulated, and the simulation inertia is calculated based on the theoretical model and the simulated vibration periods, verifying the correctness of the theoretical algorithm. Finally, a calibration device based on voice coil motor and limit mechanism is established for in-situ calibration tests of the motion simulator and analyze the main sources of errors in the tests. Experimental results show that the calibration results of the inertia of the three axes have a deviation of no more than 5% compared to the theoretical values, and the measurement error caused by the device is less than 2.5%, which is less than 1/4 of the maximum permissible error of the motion simulators. The results indicate that the calibration device can solve the problem of inertia calibration for the motion simulators of the performance testing platform.
