Dynamical Modeling of Coupled Rigid-flexible Multibody Systems Using ADAMS

Peimin Xu

Abstract

Models of rigid-flexible coupling are generic dynamical ones of multibody system.It is an important job for analysis of multibody system to explore the generic method of rigid-flexible coupling modeling.A multi-flexible body model and a rigid-flexible coupling multibody system model are established for a four-bar linkage using ANSYS and ADAMS software.Compared with the dynamic behavior of the former model,the influence of rigid-flexible coupling model on dynamic property of the system is examined and the rules of modeling are summarized.The results show rigid-flexible coupling model that its parts were treated properly can reflect approximatively dynamic property of the system at the lower modal.
