Abstract
The dynamic response of the vibration of a lunar lander to the impact of the moon surface with damping has been investigated. Based on the general analysis for landing process of the lunar lander, the dynamic model of the linear damping free vibration with multi-degrees of freedom is set up by means of the way of collision between elastic bodies. A formula concerning the vibration of the lunar lander has been obtained from a theoretical analysis. The vibration equations of the lunar lander is analyzed from the Lagrange equations. Basing on the ADAMS mechanical simulation software, a microgravity environment has been established in computer. The result has been verified by a numerical example, and the simulation result is in very good agreement with the calculated one. The conclusions obtained can be used for design and analysis of the vibrations of the lunar lander.
