摘　　要：通过分析混凝土泵车泵送系统工作原理,在AMESim软件中建立了该液压系统的仿真模型。在验证模型准确的基础上,针对某款混凝土泵车泵送系统有无缓冲结构进行了仿真对比。结果表明带有缓冲结构的泵送系统,活塞的顶缸速度比无缓冲结构的小,这样能有效地减轻泵送时的振动与冲击,对延长泵车使用寿命具有重要意义。In this paper,the working principle of the pumping hydraulic system for the Vehicle of concrete pumping is analyzed.Then it sets up the complete mathematical model of pumping circuit based on AMESim.A simulation of the pumping hydraulic system whether has a Buffer is carried out on the base of the model proved to be correct.The conclusion is that the cylinder bumping speed of pumping hydraulic system with a buffer is much lower than that without the buffer.So it can relieves the hydraulic shocking and cylinder bumping effectively,and also increase the life time of the equipment.
