摘　　要：针对三支撑月球着陆器摩擦式阻尼材料存在的真空冷焊问题,对非接触式涡流磁阻尼在月球着陆器上的应用进行了分析和试验.应用电磁学基本理论对涡流磁阻尼的基本特性进行了分析,得出了阻尼特性基本方程.使用DASP数据采集与分析软件,对新型涡流磁阻尼月球着陆器原理模型的缓冲特性进行了试验测试.结果表明,新型涡流磁阻尼月球着陆器具有较好的缓冲效果.Focused on the vacuum cold welding of friction damping materials of the lunar lander with three legs, the analysis and experiment were carried out for the application of non-contact magnetic damping of eddy current to lunar lander, Elementary characteristics of the magnetic damping of eddy current were analyzed and fundamental equations of the damping characteristics were obtained by means of electromagnetics elementary theory. Buffer characteristics of the principle models of the novel lunar lander with magnetic damping of eddy current were tested by means of the DASP software to collect and analyze data, The results show that the buffer effectiveness is very good for the novel lunar lander with magnetic damping of eddy current.
