Research on Equivalent Multi-body Dynamics Model for Nonlinear Cable Elements
摘要
Abstract
Based on the non-linear constitutive equation of the pre-loaded cable elements, this paper presented an equivalent multi-body dynamics model. In the method, the whole cable was divided into short rigid bodies, and the equivalent reaction force between the elements was deduced and applied to the rigid bodies by means of General Force in ADAMS. The torsion stiffness and damping were introduced to ensure the displacement consistent. The presented method was implemented onto ADAMS, and a pre-loaded cable model was built, the vibration amplitude and frequency under different pre-load force were analyzed, the results show that the relationship between vibration amplitude and pre-load force is agree with the analytic results. The present method provides a theoretical basis for modeling of a preload cable system using ADAMS.关键词
