| Abstract: | We take a balance circuit of hydraulic lifting system as the research object. The main structure parameters, such as load of balance hydraulic cylinder, spring stiffness and pre-stress force of balancing valve, scale of control damping orifice are calculated according to the actual working condition. A simulation model of hydraulic balance circuit is built by AMESim. The relevant simulation parameters are set and dynamic characteristics are analyzed. An experimental circuit is designed to verify the validity of simulation analysis. The results indicate that proper adjustment of structural parameters such as spring stiffness and scale of damping orifice can improve working performance of hydraulic balance circuit and provide reference for optimization design and parameter matching of hydraulic balance circuit. |
