摘要
建立了汽车燃油经济性数学模型,开发了计算仿真程序。以东风EQ140型汽车为例进行了仿真计算,仿真结果与其使用参数较为吻合;分析了其参数灵敏度,各参数对汽车燃油经济性的影响以传动系的机械效率和汽车的总质量最为显著,滚动阻力系数、空气阻力系数与迎风面积的影响则小一些。
A mathematical model of automobile fuel economy was established and its computer simulation program was compiled. The simulator calculated the fuel economy of a EQ140 type of automobile. The simulation result coincides with that was obtained from the real automobile. Parameter sensitivity was analyzed. Automobile fuel economy was influenced by a variety of parameters and the mechanical efficiency and total quality of automobile are obvious ones. The roiling resistance coefficient, air resistance coefficient and frontal area have less influence.
