摘要
本文介绍汽车的动力性、燃油经济性及传动系参数的优化设计计算机软件。该软件共有六项功能:(1)汽车加速性能模拟计算;(2)汽车在多工况循环下的燃油经济性计算;(3)汽车等速百公里油耗曲线计算;(4)汽车传动系传动比优化设计;(5)汽车主减速比优化设计;(6)汽车载重量优化设计。文中介绍了各功能的数学模型以及应用实例。
This Paper introduces the software for automobile vehicles dynamic and fuel economy calculation and transmission parameters optimal design.The software has six functions: 1.simulation calculation of acceleration performance. 2.simulation calculation of fuel economy under multi-operating cases cycle. 3.calculation of the fuel consumption curve per one hundred kilometers of constant speed operation. 4.The optimzation of gear ratios of the transmission. 5.The optimzation of rear axle gear reduction ratio. 6.The optimzatian of vehicle payload weight. This paper gives the mathematic model of each the function and practical examples.
