A Study on the Simulation of Flexible Link Mechanics : Development of a Reduction Method and Two-Node Element Including Large Displacement

Abstract

A dynamic analysis of link structures, including elastic vibrations, is presented.The two-node element including large displacement is developed.This element is based on the theory of finite rotation and includes the geometric stiffiness.The stiffness matrix and the inertia matrix are obtained from FEM model by the theory of Guyan's reduction including large displacement motion.In this paper, we explain the theory of this element and show some examples of analysis.
