Abstract

To improve the efficiency and reliability of dynamic modeling and simulation for a double-crank series crank slider press mechanism, the vector bonding graph method was proposed.According to kinematic constraint relations among mechanism components, vector bonding graph models for mechanism moving components, revolute joints and translational ones were combined to establish the whole mechanism’s vector bonding graph model.Using the effective augmented method, the differential causality in the mechanism vector bonding graph model was eliminated to overcome the algebraic difficulty brought by it to mechanism automatic modeling, and realize the mechanism’s automatic modeling and simulation.Effects of working resistance in form of pulse on the mechanism dynamic performance were analyzed, and the effectiveness of the proposed method was presented.
