1、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 concis
2、e 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 eff
3、iciency. 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 relia
4、ble, the deep users 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 concurre
5、nt 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
6、 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, impr
7、ove 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 r
8、elationship to the cars 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
9、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 b
10、y 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 Japans car companies are able to so strong, and they decades, or even hundreds
11、 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
12、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 Chinas economy in recent years, technology research and development on the investment increased significantly, from the past automob
13、ile 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, Chinas auto technology springing up rapidly. The door is the whole body structure of the complex and relativ
14、ely 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 t
15、he 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
16、 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 desig
