摘要
车门是车身结构中一个重要而复杂的总成，熟悉车门结构的功能要求、结构特点和较见的结构处理方法是车门结构设计的基础；另外，在具体的结构设计过程中，正确的方法、步骤是实现合理设计的关键，如车门总体结构的确定、附件的布置及运动校核、结构的统一协调和强度、刚度、可靠性等方面都有一定的规律和要求。
轿车门由门外板、门内板、门窗框、门玻璃导槽、门铰链、门锁及门窗附件等组成。内板装有玻璃升降器、门锁等附件，为了装配牢固，内板局部还要加强。为了增强安全性，外板内侧一般安装了防撞杆。内板与外板通过翻边、粘合、滚焊等方式结合，针对承受力不同，要求外板质量轻而内板刚性要强，能够承受较大的冲击力。
通过对国内外车身技术的发展趋势的回顾与理解，我们用现代计算机技术与国外先进的流程化设计思想，对车门基本结构与组成进行相关分析；然后我们对车门的开发流程进行了相关研究。

ABSTRACT
Car body door is an important assembly of complexity in the body structure.Structural function requirement,specialty of structure and general handling method of structure are the basis of body door structure design.In the course of door structural design,correct method and procedure are the key points to realize rational design,such as determination of door structure outlay,arrangement of accessories,motion verification and also others as overall coordination of structure,strength,rigidity,reliability etc.,all have definite rule and demand.
Car body door is composed of such as outer panel,inner panel,window frames,door glass guide slot,hinges,lock and door components accessories.The inner panel with regulator,locks and other accessories,is also necessary to strengthen local boards in order to assemble solidly.In order to enhance the safety of the door installed door beam in general. Outer panel and inner panel combine with the flange plate,bonding,roll welding.For different requirements,the quality of light outer panel and rigid strong inner panel,can withstand a greater impact.
Technology at home and abroad through the development trend of the body of the review and understanding,we do the analysis on the basic structure and the component using the modern computer technology and advanced design concepts of the process.And we carried out relevant research on the door development process.
Key words:seal，door accessory，car door，Automotive inner door panel，regulator
