摘要
针对目前月球着陆器用阻尼材料缺乏高低温条件下冲击试验数据问题,对铝蜂窝、金属橡胶及涡流磁阻尼等几种典型的阻尼材料或阻尼方式进行了高低温冲击试验研究。利用液氮实现月球低温,采用YD-12D(14)型压电式加速度传感器对铝蜂窝圆芯和金属橡胶圆环进行了测试。自制了涡流磁阻尼月球着陆器原理模型,对其缓冲性能进行了试验研究。试验结果表明铝蜂窝圆芯、金属橡胶圆环及涡流磁阻尼都可以用作月球着陆器的阻尼材料或阻尼方式使用。
Focus on the problems that lacking test data of damping materials used in the lunar lander under high and low temperature, impact experimental investigation under high and low temperature are carded out for a few kinds of typical damping materials or modes, such as aluminum honeycomb, metal rubbers and magnetic damping of eddy current etc.. Low temperature in the moon are realized by liquid nitrogen, and aluminum honeycomb core and metal rubber annulus are tested by means of YD-12（14） model piezoelectricity acceleration transducer. Experimental investigation are carried out for Buffer characteristics of homemade principle models of the lunar lander with magnetic damping of eddy current. The experimental results show that all the aluminum honeycomb core, metal rubber annulus and magnetic damping of eddy current can be used as damping materials or modes of the lunar lander.
