摘　　要：以某款混凝土泵车为研究对象,对其进行了4组转速实验,测得了每个排量脉宽下实际泵送次数。并在建立该泵送系统的AMESim模型基础上,仿真推算出了每个泵送次数所对应的斜盘开度,从而得到了4组排量脉宽与斜盘开度的对应关系。最后利用matlab软件对这4组对应关系进行了拟合,得到了排量脉宽与斜盘开度的数学关系式,从而达到了全面分析恒功率变量泵特性的目的。For variable pump opening cannot match PW pulse width accurately in concrete pump truck with PLC control,this article had a series of experiments on concrete pump truck.By doing engine speed experiments,we get a series of pumping count of each PW pulse width,so we can get four groups of relationship between PW pulse width and the pump opening.Finally fitting on four relationship was done by matlab software,and get mathematical formula of variable pump opening and its PW pulse width..
