摘　　要：对仿真试验中仿真误差的综合是给出判断仿真结果的准确度和可信度依据的重要手段。针对在对接机构半实物仿真综合试验台上进行的对接机构的地面仿真试验 ,提出了一种基于 Monte- Carlo方法的误差综合方法 ;并通过大量的仿真模拟 ,得出了对接机构地面仿真试验结果的统计规律 ;给出了仿真结果的置信区间与置信度。Synthesis of the error in simulation test is the important approach to judge accuracy and credence of simulation.Based on the Monte Carlo method,a kind of synthesis method of the error is proposed,which can be used in ground simulation test of docking mechanism implemented on the half physical synthetic simulation test bed of docking mechanism.Moreover,the statistic law of ground simulation result of docking mechanism is obtained.The confidence coefficient and the confidence interval of simulation result are given by volume simulation.The criterion for appraising accuracy and credibility of simulation results is suggested.
