摘要
分析了影响汽车性能的因素,并利用MATLAB语言开发了仿真程序。以某一车型为例进行仿真,根据发动机的外特性、汽车的加速度曲线及时间图和汽车动力特性图,得到汽车整车的动力特性和燃油经济性等参数,与实际结果吻合较好。利用仿真不仅可以快速精确地获得汽车动力性和燃油经济性分析的相应数据和图形,而且将工程技术人员从繁杂的高强度劳动中解脱出来,使其有精力和时间投入到新的工作中。
The influence factors of the automobile performance were analyzed. Simulation program of automobile performance was devel- oped based on MATLAB. According to the data of the external characteristic, power characteristics and acceleration curve-time chart of auto- mobile engine, the results of automotive dynamic characteristics and fuel economy were simulated. The simulation results coincide with actual ones. It is shown that using simulation, not only the corresponding data and graphics of automobile dynamic characteristics and fuel economy analysis can be obtained quickly and accurately, but also engineering and technical personnel extricate from multifarious high strength work, which makes them have energy and time into new projects.
