摘要
刚柔耦合是多体系统最常见的力学模型,探讨其建模规律是多体系统动力学研究的重要内容。用ANSYS和ADAMS软件为一四杆机构分别建立了一个多柔体模型和刚柔耦合模型,以前者动特性为参考,研究刚柔耦合模型对系统动态特性的影响,探索多体系统刚柔耦合建模规律。结果表明,从低阶模态来看,各构件经恰当处理后刚柔耦合模型能够较好地反映系统的动态特性。
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 multiflexible body model and a rigid-flexible coupling muhibody 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.
