车辆工程专业毕业设计汽车整车论文摘要汽车车身总布置设计是车身设计的重要内容。车身总布置设计是在整车总布置的基础上进行的, 主要包括汽车车身底版的布置、前围的布置、车身室内人体工程布置、车门布置、发动机舱、行李舱的布置以及其它装备的布置。其中车身室内人体工程布置是主要的内容涉及到人体工程学的知识。可以说车身总布置设计的好坏是决定车身设计和轿车设计好坏的一项重要内容。本次 7161 轿车车身总布置设计主要是利用已给的数据和人体工程学的基本知识对该车型的车身外形布置和内部布置进行设计, 并进行相关的动力性和经济性计算以检验设计的合理性。通过本次毕业设计, 充分了解和掌握了对某一轿车车身进行车身总布置设计的步骤和方法,这将为我们以后毕业从事汽车车身设计的工作打下基础。关键词:车身总布置设计人体工程学车身外形布置设计车身室内布置设计 Abstract Car body general arrangement design is an important constituent of car body design. It is on the basement of car general arrangement design, includes car floor arrangement 、 front fender arrangement 、 interior body ergonomic arrangement 、 door arrangement 、 engine module and partment arrangement and other establishments arrangement. Among them, the interior body ergonomic arrangement is the most important part as it relates to ergonomics. We can say that the quality of car body general arrangement is an important constituent which determines the quality of body design and car design. During this time ’s Ao Tuo mini car body general arrangement design, the mainly part of my work is to use data which is given by my guiding teacher and the infrastructural knowledge of ergonomics to design Ao Tuo car body external and interior arrangement, and to conduct some calculation about this car ’s power and economy performance. This calculation can check that whether the car body general arrangement design is reasonable or not. Through this graduate design, I fully know and master the steps and methods of body general arrangement design toa specific car body, which will lay the foundation for our car body design work after graduation. Key words : body general arrangement design ergonomics body external arrangement design interior body arrangement design 1. 绪论 汽车设计的规律,决策与设计过程汽车设计尤其是新新车型的设计, 是根据社会对该车型的使用要求而提出的整车参数与性能指标进行计算的, 显然, 那只能从宏观入手, 即从整车的总体设计开始, 然后通过总体设计的分析与计算, 将整车参数和性能指标分解为有关总成的参数和功能后, 再进行总成和部件设计,进而进行零件甚至某一更细微的局部设计与研究。汽车设计过程: 1) 调查与初始决策:其任务是选定设计目标,并制定设计工作方针及设计原则。调查研究的内容应包括: 老产品在服役中的表现及用户意见; 当前本行业与相关行业
