摘　　要：在汽车设计过程中,整车动力性能分析是最重要和最基本的研究内容,本文结合国产某汽车的设计参数,利用Simulink搭建驱动力与行驶阻力平衡模型和动力特性模型进行仿真,并且通过Matlab进行数据处理与绘图结果输出,获得汽车行驶的最高行驶车速、最大加速度以及最大爬坡度等评价性指标。经过仿真与试验数据的对比分析,证明仿真结果与试验数据误差小,数据可靠,反映汽车真实行驶路况的动力性特征。因此,该方法可作为设计汽车动力性能的一种依据。In the process of automobile design,the analysis of the whole vehicle dynamic performance is the most important and basic research content.In this paper,it describes that use Simulink to build the drive force and driving resistance balance model and power characteristics model with the design parameters of a domestic automobile,as well as use Matlab to process the data and output the plotting results to find out the maximum driving speed,maximum acceleration,maximum climbing degree and other characteristics of the car.After comparison and analysis,the data are reliable,reflecting the dynamic characteristics of the real driving road conditions of the car with small errors.Therefore,the method can be used as a basis for design the dynamic performance of a car.
