摘　　要：本文针对梁底悬挂运梁装备在桥梁底部的两个平行导轨上存在双液压缸同步运动的这一问题,提出了推拉油缸液压控制系统,建立了此液压控制系统AMESim仿真模型,基于传统的“主从方式”,通过研究调节比例流量阀的开闭口大小,来控制此液压系统中的流量大小;研究蓄能器作为辅助动力源,向从动缸提供一定流量的液压油,达到主从动缸同步的效果。仿真结果表明:此液压系统改变了传统的同步液压系统调整时间长、动态性能差等缺点,在两个比例阀流量分别为8 L/min,11 L/min,蓄能器压力为128 bar,负载在0~50t时可以使前拉油缸与后推油缸达到同时伸出与同时收回的结果。Aiming at the bottom of the beam suspension hoisting equipment on the bridge at the bottom of the two parallel guide rail is double hydraulic cylinder synchronous movement of the problem,put forward the push-pull cylinder hydraulic control system,established the AMESim simulation model of the hydraulic control system,based on the traditional"master-slave mode",by studying the regulation of proportional valve open mouths size,To control the flow rate in the hydraulic system;The accumulator as an auxiliary power source provides a certain flow of hydraulic oil to the driven cylinder to achieve the synchronization effect of the master and slave cylinders.The simulation results show that the hydraulic system overcomes the disadvantages of the traditional synchronous hydraulic system,such as long adjustment time and poor dynamic performance.When the flow rate of the two proportional valves is 8 L/min and 11 L/min respectively,and the accumulator pressure is 128 bar,and the load is 0~50 t,the forward pull cylinder and the back push cylinder can reach out and withdraw simultaneously.
