A Study on the Stability of Lunar Lander Based on The Deformation of the Buffering

摘要

In the overall study of the design and performance of the lunar Lander, analysis of touchdown dynamics of the landing stage is an important part. In this paper ,the rigid-flexible coupling dynamics of a system consisting a flexible cantilever attach to the main Lander is analysis, The equations with the flexible part are derived from the subsystem method reported . Results show that the deformation of cantilever has a considerable effect on the stability of the Lunar Lander system.
