摘　　要：为更好地研究使用抗流量饱和液压系统(LUDV)控制的挖掘机动臂的工作特性,对LUDV系统及其使用的负载补偿多路阀进行建模和分析,在多体动力学仿真软件Simulation X中建立动臂阀联的多体动力学模型,研究了多路阀动臂阀联的通流面积特性及其在空载工况下的运行特性。研究表明多路阀动臂阀联通流面积与其适用的液压缸油腔面积一致,其设计可以满足控制要求,但在大惯性工况下使用该阀会存在压力波动。In order to research the working performance of the hydraulic excavator boom with flow-saturated resistant system （LUDV）,the LUDV system and the valve are modeled and analyzed.The research of the flow area and working performance without load of the boom valve under they are modeled with the multi-body software SimulationX.The result shows that the flow area of the boom valve is in agreement with pistion area of the cylinder used in the system,and the design of the valve can meet the control requirements.But there will be pressure fluctuations in the large inertia conditions as the boom is working.
