摘 要
自人类进入工业时代,社会就在快速的发展,在当下,传统的燃油车不断面临各种危机和挑战,而电动车和智能车正在被世界各国政府所青睐和支持鼓励,这是很有必要的,这可以帮助我们缓解能源短缺以及环境破坏等问题,此外,电动车和智能驾驶是目前国际上研究的热点。由此,我们国家也在这些方面极力支持,本文就这种趋势下,为一辆将开发的靶车做了相关的分析。
本文为开发一辆自动驾驶轻型电动车做了相关参数的选择和优化,并对相关性能做了仿真分析。首先,本次毕业设计的车辆的参考车型是一辆装甲车外形的靶车,再在这个基础上进行相关的总布置设计。其次,寻找类似本次设计的大量书籍和参考文献来对靶车的需要的车辆参数进行了大致的选择;接着,因本人选择将该车设计为纯电动车,故对其驱动系统进行了详细的选择和设计计算,并对其他重要的总成进行了类型的初步确定;然后,因该靶车是智能车,故对其进行了相关传感器的选择;最后,利用仿真工具ADVISOR 2002对此次设计的车辆进行了动力性和经济性(续驶里程)的相关仿真分析并对相关参数做了优化,同时借助仿真软件CARSIM 2019对靶车的制动性、操纵稳定性、平顺性进行分析。在这个过程中,对软件仿真分析的结果进行分析,我们可以初步判定设计的结果是比较符合预期的,可以作为有关设计人员的参考。
利用计算机软件进行分析,这是一种很好车辆分析方法,可以很好的节约成本,本文最后利用CATIA和CAD软件对靶车进行了相关建模,对其底盘、车身、驾驶员内部布置进行了相关布置分析。这对靶车设计,有着重要的参考意义。

Abstract
Since humanity entered the industrial age, society has been developing rapidly. At present, traditional fuel vehicles are constantly facing various crises and challenges, and electric vehicles and smart vehicles are being favored and supported by governments around the world. This can help us alleviate problems such as energy shortages and environmental damage. In addition, electric vehicles and intelligent driving are currently hot research topics in the world. Therefore, our country also strongly supports these aspects. Under this trend, relevant analysis was made for a target vehicle to be developed.
This paper selects and optimizes relevant parameters for the development of a self-driving light electric vehicle, and makes a simulation analysis of the relevant performance. First of all, the reference model of the vehicle designed for this graduation is a target vehicle with an armored vehicle shape, and then the relevant general layout design is carried out on this basis. Secondly, looking for a large number of books and references similar to this design to make a rough selection of the vehicle parameters required by the target vehicle; then, because I chose to design the vehicle as a pure electric vehicle, its drive system was detailed Selection and design calculations, and preliminary determination of the types of other important assemblies; then, because the target car is a smart car, it has selected the relevant sensors; finally, using the simulation tool ADVISOR 2002 The designed vehicle was simulated and analyzed for power and economy (remaining mileage) and related parameters were optimized. At the same time, the simulation software CARSIM 2019 was used to analyze the braking performance, handling stability and ride comfort of the target vehicle. In this process, by analyzing the results of software simulation analysis, we can preliminarily determine that the design results are more in line with expectations and can be used as references for relevant designers.
Using computer software for analysis, this is a very good vehicle analysis method, which can save costs very well. Finally, this paper uses CATIA and CAD software to carry out relevant modeling of the target vehicle, and its chassis, body, and driver's internal layout Related layout analysis. This has important reference significance for target vehicle design.
