摘　　要：针对HBT60型混凝土泵出现摆阀液压缸换向停顿的故障,分析其泵送液压系统的工作原理,利用功率键合图的建模方法建立相应的数学模型,并运用MATLAB/Simulink仿真工具箱对故障特性进行仿真。仿真结果表明引起摆阀液压缸换向停顿故障的根本原因为逻辑取信阀弹簧刚度过大及单向阀弹簧预紧力过大,对相关参数进行调整后,故障现象得以消除。in view of fault stoppage in a hydraulic swing cylinder at an HBT60 concrete pump working principles of the hydraulic pumping system has to be analyzed by using model construction of the power graph bond to have built a responsible analog while utilizing MATLAB/Simulink simulating kit to simulate traits of the trouble.Simulation results show that the trouble's root cause lies in over rigidity of the logic signal picking spring and pre-set force of the one-way spring,respectively.However,such a fault has been remedied after readjusting the relevant data.
