Research on Dynamic Performance Simulation of Hydraulic Crane System Based on AMESim-Simulink
To improve the dynamic performance of hydraulic lifting system,a hydraulic balance valve was used as the core compo-nent to analyze its three working states.A hydraulic lifting system with pump valve collaborative control was designed,and a balance valve and hydraulic lifting circuit model were built using AMESim-Simulink.The simulation results show that when the hydraulic lifting system controlled by the balance valve is in a small flow and small load condition,the transition process from static to descending of the load results in large speed peak and slow speed stability.Compared with the hydraulic lifting system only controlled by the balance valve,the hydraulic lifting system based on fuzzy PID pump valve collaborative control has smaller speed overshoot and shorter speed stability time under small flow and small load conditions.
