汽车动力性和经济性计算.doc

摘要
汽车运用工程课程是交通运输本科专业的一门主干课程,而对于汽车来说,动力性与经济性是两个非常重要的指标,它们能综合反映出某一款车的性能高低。本文正是通过计算一款车( MT 舒适型)的动力性能以及燃油经济性来确定该款车的性能是否得到充分发挥,同时利用计算机VB高级语言编程,以此为基础,对其传动系参数进行了优化,通过对优化前后整车性能的对比分析,判断是否达到在动力性能与燃油经济性之间达到一个较优平衡。相信通过这次的汽车运用工程课程设计,我将会更深层次地理解汽车各性能。
Abstract
Automobile Application Engineering undergraduate curriculum is a transport main course, and for the car, power and economy are two very important indicators, which prehensively reflect the performance of a particular level of a car. This article is by calculating a car (new Tiggo fort) of the dynamic performance and fuel economy to determine whether the performance of the car is brought into full play, while taking advantage of high-puter programming language VB as a basis, its transmission parameters were optimized paring before and after optimization of vehicle performance, to determine whether the dynamic performance and fuel economy to achieve an optimal balance between. I believe that through the use of the automobile engineering course design, I will be a deeper understanding of the performance car.
