摘　　要：为了解决三支撑月球着陆器在不同着陆月面情况下的缓冲性能问题,对月球着陆器模型样机进行了试验研究.使用自制仿月壤,在不同月面倾角情况下进行了多次着陆试验.采用压电式加速度传感器及DASP数据采集与分析软件对三支撑月球着陆器原理样机缓冲性能进行了试验测试.结果表明:使用金属橡胶作阻尼材料的三支撑月球着陆器具有良好的缓冲效果,其冲击隔离系数<0.2.In order to slove the problems of buffer characteristics of lunar lander with three legs landing on different moon surfaces, experimental investigations are carried out for prototype of lunar lander. Multiple landing tests are finished on the condition of different oblique angles of the moon surface by means of simulation lunar soil made by ourselves. Testing for buffer characteristics of the prototype of lunar lander with three legs are finished by means of piezoelectricity acceleration transducers and the DASP software which may collect and analyze data. The results show that buffer characteristics of the lunar lander having metal rubber damping, materials with three legs are excellent and the imnact isolation coefficients are less than 0.2.
