Touchdown dynamic modeling and simulation of lunar lander
In this paper, the key influences of lunar lander landing model are illuminated systematic. Then the touchdown dynamic model of lunar module is built. And the simulation model for lunar landing described on ADAMS is discussed. As an example, one kind of lunar module model with four cantilever truss style landing gear is built by ADAMS and the simulations are focused on the influences on landing by the characteristics of buffers in primary and secondary struts of the landing gear. The conclusions can be used for the design of lunar lander.
Research of the Factors of Buffering Performance in Lunar Lander
Honeycomb as a new type of a material have an extensive practice in soft landing of lunar Lander.In this paper,firstly,considering the large deformation of the honeycomb,the dynamics of the secondary buffering in lander was carried in LS-DYNA.Secondly,the rigid-flexible couplings dynamics of a system consisting a flexible fuselage attach to the main Lander are analysis.The result shows that when the first honeycomb material is completely compressed in step buffer,the impact acceleration is largest.The deformation of fuselage has a considerable effect on the stability of the Lunar Lander system.This research can be beneficial to the second lunar probe in china.
