为了分析混凝土泵车臂架液压系统的动态特性,根据混凝土泵车臂架液压系统工作原理,建立了混凝土泵车臂架液压系统AMESim仿真模型,对混凝土泵车臂架系统收回过程进行了动态仿真,得到了各个臂架液压缸的压力曲线、流量曲线和活塞位移曲线.仿真结果对混凝土泵车臂架液压系统的设计有一定的指导作用.

英文摘要：

For analyzing the dynamic characteristic of the hydraulic system of the concrete pump truck＇s arm, according to the operating principle of the hydraulic system of the concrete pump truck＇s arm, the simulation model of the hydraulic system of the concrete pump truck＇s arm was established by using AMESim, which was carried out to simulate the concrete pump truck＇s arms＇ retracting process, and the pressure and flowrate as well as piston displacement curve of each arm cylinder were obtained. The simulation results are helpful to design of the hydraulic system of the concrete pump truck＇s arm.
