摘要

The purpose of this paper is to do some researches on the accurate shape description of flexible beam undergoing oblique impact based on space probe-cone docking mechanism. The docking dynamics model is built based on Lagrange analytical method. Accurate modal equations of rigid flexible coupling system, which include modified modal equations and modal frequencies, are derived. The MSC.Patran/Dytran is introduced to be the simulation tool. Third models with different parameters are built by both theoretical method and finite element method to verify the correctness of the new modal equations of rigid flexible coupling system.
