| Abstract: | 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. |
