摘要: 针对航天器高精度地面微重力仿真试验实现难题,提出了一种基于等效动力学原理的垂向失重运动实现方法。通过对该实现方法的原理分析,指出了该方法实现高精度垂向失重运动模拟的等效动力学条件及其适用条件,并分析了基于该实现方法的模拟器构型要求。对模拟误差精度进行仿真分析,结果显示其失重运动模拟精度可达99%,满足高精度微重力仿真试验的要求。
英文摘要: For the difficulty on spacecraft ground simulation of high precision microgravity, a vertical weightless movement method based on equivalent dynamics was proposed. The equivalent dynamics and its conditions were brought forward to implement high precision vertical weightless movement simulation. Then, the simulator design requirements based on the proposed method were analyzed. Through simulation analysis of the simulation accuracy, the possible problems of the design principle were discussed. Error analysis and simulation calculation results show the weightlessness simulation accuracy is up to 99%,which can satisfy the requirements of the high precision microgravity simulation experiment.
