基于CRUISE软件某燃油车动力系统建模与匹配

Improvement Design of Torque Fluctuation of the Electric Vehicle Steering System

汽车动力系统的匹配,决定着汽车动力性能和经济性能的好坏,决定着所选动力的有效发挥。这一性能主要取决于发动机特性、传动系参数,以及这二者之间的相互匹配。文章通过AVL-CRUISE软件建立整车仿真模型,并对提供的四个发动机和两个变速器进行合理地匹配,并比较匹配结果的动力性和经济性,找到一种最佳的匹配方案。

Matching of the vehicle power system,determine the car's dynamic performance and economic performance,determine the effective play of the selected power.This performance mainly depends on matches of the engine characteristics and train parameters.This paper through AVL-CRUISE software build a vehicle simulation model,There are four engines and two transmissions,the purpose of the task is reasonable matching between four engines and two transmission.At last,compare the results of the match performance and fuel economy,a best match scheme can be find.
