Car door industry overview
Now automotive upgrading of products are quick and every style of the design of the car as a systems engineering, is relatively independent process, many multinational auto company decades ago has already broken the relative independence, the design of every process concise ascension, make a module, according to the method of system to organize and defined as car design process. In the later new car design, each process into the established design patterns, step by step, control the car promote each a very detailed design process, thus well to complete the design efficiency. At home, faw, no.2, saic big auto enterprise group has been established a comparatively perfect product design process, in home increasingly fierce competition in the automobile products, the enterprise product competitiveness, the obvious advantage of product update speed, quality is reliable, the deep user's trust, and the establishment of research and development process of is the important significance of enterprise.
With the car body modelling design and changes required increased day by day, parameter design more accord with and close to the modern CAD concept design and concurrent design thought, and can improve the design and analysis of flexible body, so the model parametric design vehicle manufacturing industry has become an inevitable trend. Parametric design is a new way of thinking to the products and the design methods of modification and. At present the traditional manual modelling method has been established in various kinds of advanced modelling modeling software on the basis of the computer aided modeling method, replaced parametric design technology can be quickly absorb foreign auto body design of advanced technology, rapid response in China market, improve the ability of independent design and development, improve the car auto product competition ability.
With the development of automobile industry, automobile comfort still improve to satisfy the requirement of people. The car door is relatively independent assembly, the car door design not only relationship to the car's practical, to cars also have very big adornment effect. So the design of the door also more and more exquisite, and use more and more
network and electronic technology. From 1957 new China first cars officially production line, China automobile in the middle of the twentieth century experienced a long and slow development stage, after the 2003 and 2006 after two rounds of BaoFaShi growth, begin entering the steady growth stage. The severe macroeconomic situation, the development of the Chinese car industry is facing unprecedented challenges and opportunities, but also by the impact of the from all sides. China will want from car manufacturing power development become automobile industry power, it must in the research and development of product of car a breakthrough. Europe, the U.S. and Japan's car companies are able to so strong, and they decades, or even hundreds of years of technical innovation and accumulate experience is not divided, flipping them the history of the development of automobile industry, we can clearly feel they the same enterprise development context: clear market positioning, determined the technical research and development, leading the trend of the strategic direction, it all, make enough of their primitive accumulation. We start though some late, but the car industry as one of the main industries of China's economy in recent years, technology research and development on the investment increased significantly, from the past automobile products imported into product introduction production to the technical transformation, in the last few years is more direct technology import and merger advanced foreign auto enterprise, China's auto technology springing up rapidly.
The door is the whole body structure of the complex and relatively independent a assembly, it mainly by the door frame and cover plate and the doors, Windows, and protective glass and glass door, door lock and handle, drive the car door hinge, door and door article seal structure switch. The door is the car body design of a relative independent components. In the door design its safety is especially important, it must guarantee in the vehicle collisions, as far as possible to reduce to pedestrians and crew of the damage the car door, and therefore must be requirements covering parts surface is bright and clean and tough; Door lock, door hinge and the door door body must be able to A column in A column B A C pillars of collision impact; relay route After the collision of the door must be able to easily not rely on any auxiliary tools with open hand. In view of the side impact caused by the crew of risks in the car, pay attention to the design of the car deformation limits within a certain range, crew to provide a valid living space. These require the door must have the enough strength and rigidity. In the car body design's process, the doors of the assembly and design layout design in addition to coordinate the relationship with, but said the is a
relatively independent, is the most representative body assemblies design. It should not only and vehicle modelling coordinated, it also ensures that the necessary opening, convenient hop on and off, good security, stability, seal, handling technology, enough strength and stiffness, to meet the functional requirements. So the design of the door a body design one of the important links.
Manufacturers in order to be in the market competition in an invincible position, we must improve the product quality, reduce the production cost, shorten the development cycle of the products, to improve labor productivity, all of these forced to seek the intelligent designer constantly design tools and advanced design method. This topic research content that is in such cases of generation.
汽车车门行业概述
如今汽车产品的更新换代速度很快，而每一款汽车的设计作为一个系统的工程，是相对独立的过程，很多跨国汽车公司早在几十年前就已经打破了这种相对的独立，将设计的每一个过程凝练提升，形成一个个模块，按照系统的方法组织起来，定义为汽车设计流程。

在以后的新车设计中，将每一个过程融入了这种既定的设计模式，按部就班地推进，控制着汽车的每一个非常详细的设计过程，从而顺利高效地完成设计。

在国内，一汽、二汽、上汽等大的汽车企业集团都已经建立起了比较完善的产品设计流程，在国内愈演愈烈的汽车产品竞争中，这些企业的产品竞争力有着明显的优势，产品更新速度快，质量可靠，深得用户的信赖，可见研发流程的建立对企业的重要意义。

伴随着汽车车身造型的设计与修改要求日趋增高，参数化设计更符合和贴近现代CAD中的概念设计和并行设计思想，并可提高设计与分析的柔性，因此车身模型的参数化设计经成为车辆制造行业发展的必然趋势。

参数化设计是以一种全新的思维方式来进行产品的创和修改设计的方法。

目前传统的手工造型方法已被建立在各种先进的造型建模软件基础上的计算机辅助造型方法所取代，参数化设计技术能够快速吸收国外汽车车身设计的先进技术，快速响应市场，提高我国自主设计开发汽车的能力，提高汽车产品竞争能力。

随着汽车技术的发展，汽车的舒适性不断提高以满足人们的要求。

汽车车门是车上相对独立的总成，车门设计不但关系到汽车的实用性，对汽车也有很大的装饰作用。

因此车门的设计也越来越讲究，而且使用越来越多的网络和电控技术。

从1957年新中国的第一辆汽车正式生产下线，中国汽车在20世纪中期经历了漫长的缓慢发展阶段，在经过2003年和2006年的两轮爆发式增长后，开始步入平稳增长阶段。

2009年严峻的宏观经济形势下，中国汽车行业的发展面临着前所未有的挑战与机遇，同时也受到来自各个方面的冲击。

中国要想从汽车制造大国发展成为汽车产业强国，就必须在汽车产品的研发上取得突破。

欧美日的汽车企业之所以能够如此强势，与他们几十年甚至上百年的技术革新与经验积累是分不开的，翻开他们汽车产业发展的历史，我们都能够清晰的感受到他们相同的企业发展脉络：明确的市场定位，坚定不移的技术研发，引领潮流的战略方向，这一切，做足了他们的原始积累。

我们的起步尽管有些晚，但是汽车产业作为中国经济的支柱产业之一，近年来在技术研发上的投入力度明显增加，从过去的汽车产品进口到产品引进生产再到技术转化，近几年来更是直接的技术引进、并购国外先进的汽车企业，中国的汽车技术如雨后春笋般迅猛发展。

车门是整个车身中结构复杂又相对独立的一个总成,它主要由车门骨架及盖板、车门护面、门窗、车门玻璃及玻璃升降器、门锁及其手柄、车门铰链、车门密封条和车门开关机构组成。

车门是汽车车身设计中的一个相对独立的零部件。

在车门设计中其安全性尤为重要，它必须保证在车辆发生碰撞时，尽可能地减少对行人和乘员造成的伤害，因此必须要求车门外覆盖件表面光洁、有韧性；门锁、门铰链以及车门门体必须能够按照A柱一B柱一C柱的路线传递碰撞冲击力；碰撞后的车门必须能够轻松地不借助于任何辅助工具用手打开。

鉴于侧面碰撞对乘员造成的危险性，在设计车门时注意将车门的变形限制在一定范围内，为乘员提供一个有效的生存空间。

这些都要求车门必须具备足够的强度和刚度。

在汽车车身设计的过程中，车门总成的布置设计除与整体设计有着协调配合关系外，可称的上是一个相对独立的，最具有代表性的车身总成设计。

它不仅要与整车造型协调一致，还要保证必要的开度，方便上下车，良好的安全性，稳定的操纵性，密封性，工艺性，足够的强度刚度，以满足功能上的要求。

因此车门的设计成为车身设计中的一个重要环节。

生产厂家为了能在市场竞争中立于不败之地，就必须提高产品质量，降低生产成本，缩短产品的开发周期，提高劳动生产率，所有这些迫使设计者不断地寻求智能化的设计工具和先进的设计方法。

本课题的研究内容就是在这样的情况下产生的。
