The Modeling and Simulation Analysis on Four Corners Leveling System in Composite Material Hydraulic Press Based on AMESim/ADAMS
Authors: , , ,
Abstract: Four corners leveling system is one of the key parts of composite material hydraulic press, whose performances determine the pros and cons of the pressing performances. Electro-hydraulic control system is the most critical aspect in affecting the control characteristics. The kinematics and dynamics models of four corners leveling system based on ADAMS were established, while electro-hydraulic control system model based on AMESim was built. The above-mentioned simulation models formed the united simulation models for four corners leveling system. The effects of key parameters on control characteristics, including the dead zone and hysteresis of proportional valve and the hydraulic cylinder leakage, were analyzed by simulation, and the influence laws of various parameters on the synchronization control precision were obtained. Simulation results show that the single cylinder, double-cylinder or multi-cylinder existing dead zone and hysteresis and leakage can affect the synchronization error. Comparing with the working condition of single cylinder, the multi-cylinder with dead zone, hysteresis and leakage can significantly cause larger synchronization error.
