摘　　要：为研究三缸内燃式水泵的外特性,对主运动系统和配流阀系统进行动力学分析,建立了动力学模型。采用AVLBoost软件和MATLAB语言,对三缸内燃式水泵在油门全开时的燃油消耗率、有效热效率和运转不均匀度等外特性进行了仿真研究,给出了仿真曲线。并与发动机驱动柱塞泵系统的外特性进行了对比分析,结果表明三缸内燃式水泵的燃油消耗率和运转不均匀度明显低于发动机驱动柱塞泵系统,而有效热效率明显高于发动机驱动柱塞泵系统。在容积效率较高的1600～1800 r/min范围内,燃油消耗率较低,比发动机驱动柱塞泵系统的燃油消耗率要低17%。对油门全开时的燃油消耗率进行了试验验证并与仿真结果进行比较,相对误差均在±5%以内,验证了模型与仿真结果的正确性。The dynamic analysis of main body and valve type orifice system was conducted and the dynamic models were developed for studying external characteristics of three-cylinder internal combustion water pump.Fuel consumption,effective thermal efficiency and running unevenness at full throttling were simulated through AVL Boost and MATLAB software.The curves of simulation were drawn.The external characteristics of three-cylinder internal combustion water pump were compared with those of engine driving pump system...
