摘　　要：针对未来目标天体表面低重力场模拟,推导了探测器软着陆动力学相似性关系,提出了一种通过改变探测器着陆初始条件,并对试验数据进行后续处理来模拟目标天体表面低重力场的新方法,通过算例验证了该方法对于不同的探测器状态及土壤状态均具有广泛的适应性。通过该方法进行探测器的相关低重力场模拟试验,可以使用探测器原型且试验设备简单、操纵容易,具有很强的实用性,方便进行探测器主要参数的优化设计,该方法可用于后期月球探测、火星探测及其他地外天体低重力模拟试验中。The difficulty of landing-impact tests of the lunar lander is the simulation of low-gravity field on the surface in lunar environment, this paper derived the law of dynamic similarity for landers, and propose a new method for simulating low gravity field on the surface of objects outside earth, which was achieved by changing initial conditions of probe landing and by subse- quent treatment of experimental data. And also the widely applicability to different lander conditions and lunar soil conditions is proved by calculation examples. Through this method to simulate the low gravity, the prototype of lander can be used with simple equipment and can be made optimization very easily. This method can be used for later lunar exploration, the Mars ex ploration and low gravity simulation on other extraterrestrial objects.
