Abstract : In this paper, dynamic simulation and analysis for designing the soft landing of a lunar lander is focused. The primary objective of the lunar lander is to land safely on the surface of moon, without causing the lunar lander to topple and must attenuate the landing loads to preclude damage to the lander structure. The dynamic structural model of lunar lander is modelled and simulation described on Multi-body Dynamics software MSC ADAMS is discussed. The lander has important features of spring and damper system as shock absorber on the primary struts for energy absorption. To obtain the safe landing, various configuration design parameters are considered such as coefficient of friction, initial touchdown vertical and horizontal velocity components, lunar slope and crushing force of energy absorbing material in the leg struts. Effects on vehicle landing stability due to variations in vehicle velocity, orientation and the surface slope are discussed.
