摘　　要：针对液压双缸同步系统在偏载情况下同步性能较差的问题进行了研究,提出引入负荷传感技术调节系统压力的方法,使得系统流量不受负载变化影响,从而达到双缸同步。阐述了负荷传感液压双缸同步系统的组成及工作原理,建立了负载敏感泵、多路阀及整个系统的AMESim模型,并验证了模型的正确性。对模型的仿真分析表明:单个油缸动作时,系统流量不受负载变化影响,油缸速度保持恒定;双缸同步动作时,两回路流量不受偏载影响,当输入信号相同时,双缸保持同步。The research is for the problem of poor synchronization performance of two cylinders hydraulic Synchronization system under partial load situation.The method of adjusting the system pressure by using load-sensing technology that can make the system flow out of influence by load changes and finally achieved synchronization is brought up.The component and basic principles of a Load-sensing hydraulic synchronous system is introduced.The load-sensing pump、multi-way valve and entire system AMESim model is established.And the correctness of the model is verified.Simulation results reveals that when the single cylinder moves,load-changing doesn＇t affect the system flow and the speed of cylinder is stable.When the two cylinders move,the two-loop flows doesn＇t influenced by partial load.When the input signals are the same signal,the two cylinders achieve synchronization.
