为解决着陆器研发过程中着陆稳定性、能量吸收和载荷缓冲等问题,需要开展大量的软着陆动力学仿真分析。文章研究分析了过去几十年中,腿式月球着陆器软着陆动力学仿真数学模型的发展过程及一些最新的建模方法。针对软着陆动力学仿真数学模型的3个方面：着陆器模型、月面模型和着陆腿足垫与月壤的接触模型,给出了各种建模方法之间的联系,并对着陆动力学仿真绝对性能分析方法和统计分析方法进行了讨论。根据文献调研分析情况,提出了应采取的着陆动力学建模与分析方法的指导性建议,并提出了有待于进一步研究和发展的问题。

Soft landing dynamic simulation is a key to support the development of lunar lander in the areas of landing stability,energy absorption and landing load attenuation.This paper analysizes the development of mathematical models for soft landing dynamic simulation of legged-type lunar lander in the past decades and latest modeling approaches.Mathematical models of soft landing dynamic simulation are comprised of lander model,lunar surface model and footpad-soil interaction model.The relations among different modeling method are summarized,and absolute-performance analysis method and statistical analysis method are discussed.Based on the assessment of literature survey,suggestions of lunar landing dynamic modeling and analysis methods are proposed,and recommendations on the needed enhancements to the state of art are given as well.
