A Novel Flexible Assistant Parallel Mechanism and Dynamic Analyses

摘要：

Due to the existence of the hinge, the parallel mechanism’s high precision and high stiffness’ characteristics in theory have been greatly affected. Based on a kind of 4-DOF parallel mechanism for cutting and the principle of prestressing to additional fixed tension flexible servo mechanism, the paper presents a novel flexible assistant parallel mechanism and then the new mechanism characteristics are analyzed. Each sub chain is formulated with the D-H coordinate, and then the dynamic model is established with Newton - Euler method. Finally the paper simulates the dynamic model by the Matlab software. The simulation results indicate the mechanism’s dynamic character
