对接机构方案样机轴向缓冲力仿真分析与试验验证

在对接机构方案样机缓冲试验中发现了轴向缓冲力超标的问题. 针对这一问题, 理论分析了轴向缓冲力过大的原因, 进行了仿真计算, 给出了降低轴向缓冲力的措施, 并在对接机构方案样机上实施了部分措施进行验证试验, 验证试验数据表明仿真正确、措施有效. 仿真也复现了飞行器模拟件自振频率对轴向缓冲力的影响, 并在飞行器模拟件的模态测试中得到了验证, 仿真给出了必须对试验数据进行滤波分析的结论. 

Contact Force Simulation and Test Analysis of Docking Mechanism

During the course of docking dynamic test,the contact force is beyond the index.Math model is built to simulate the test process,and the suggestion is given to solve the problem.Accord- ing to the math simulation results,modified components were assembled to the docking systems. Finally,the results of the math simulation indicate that the force data contains the structure fre- quency information,and the later modal test for the spacecraft simulators validates the math model, and the suggestion is given that...
