黑龍江工程學院本科生畢業(yè)設計 1 附 錄 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 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 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 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 黑龍江工程學院本科生畢業(yè)設計 2 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 Japans 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 Chinas 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, Chinas 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 designs process, the doors of the assembly and design layout design in addition to coordinate the relationship with, but said the is a 黑龍江工程學院本科生畢業(yè)設計 3 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. 黑龍江工程學院本科生畢業(yè)設計 4 汽車車門行業(yè)概述 如今汽車產(chǎn)品的更新?lián)Q代速度很快，而每一款汽車的設計作為一個系統(tǒng)的工程，是相對獨立的過程，很多跨國汽車公司早在幾十年前就已經(jīng)打破了這種相對的獨立，將設計的每一個過程凝練提升，形成一個個模塊，按照系統(tǒng)的方法組織起來，定義為汽車設計流程。在以后的新車設計中，將每一個過程融入了這種既定的設計模式，按部就班地推進，控制著汽車的每一個非常詳細的設計過程 ，從而順利高效地完成設計。在國內(nèi)，一汽、二汽、上汽等大的汽車企業(yè)集團都已經(jīng)建立起了比較完善的產(chǎn)品設計流程，在國內(nèi)愈演愈烈的汽車產(chǎn)品競爭中，這些企業(yè)的產(chǎn)品競爭力有著明顯的優(yōu)勢，產(chǎn)品更新速度快，質(zhì)量可靠，深得用戶的信賴，可見研發(fā)流程的建立對企業(yè)的重要意義。 伴隨著汽車車身造型的設計與修改要求日趨增高，參數(shù)化設計更符合和貼近現(xiàn)代CAD中的概念設計和并行設計思想，并可提高設計與分析的柔性，因此車身模型的參數(shù)化設計經(jīng)成為車輛制造行業(yè)發(fā)展的必然趨勢。參數(shù)化設計是以一種全新的思維方式來進行產(chǎn)品的創(chuàng)和修改設計的方法。目前傳 統(tǒng)的手工造型方法已被建立在各種先進的造型建模軟件基礎上的計算機輔助造型方法所取代，參數(shù)化設計技術能夠快速吸收國外汽車車身設計的先進技術，快速響應市場，提高我國自主設計開發(fā)汽車的能力，提高汽車產(chǎn)品競爭能力。 隨著汽車技術的發(fā)展，汽車的舒適性不斷提高以滿足人們的要求。汽車車門是車上相對獨立的總成，車門設計不但關系到汽車的實用性，對汽車也有很大的裝飾作用。因此車門的設計也越來越講究，而且使用越來越多的網(wǎng)絡和電控技術。 從 1957年新中國的第一輛汽車正式生產(chǎn)下線，中國汽車在 20世紀中期經(jīng)歷了漫長的緩慢發(fā)展階段，在經(jīng)過 2003年和 2006年的兩輪爆發(fā)式增長后，開始步入平穩(wěn)增長階段。 2009年嚴峻的宏觀經(jīng)濟形勢下，中國汽車行業(yè)的發(fā)展面臨著前所未有的挑戰(zhàn)與機遇，同時也受到來自各個方面的沖擊。中國要想從汽車制造大國發(fā)展成為汽車產(chǎn)業(yè)強國，就必須在汽車產(chǎn)品的研發(fā)上取得突破。歐美日的汽車企業(yè)之所以能夠如此強勢，與他們幾十年甚至上百年的技術革新與經(jīng)驗積累是分不開的，翻開他們汽車產(chǎn)業(yè)發(fā)展的歷史，我們都能夠清晰的感受到他們相同的企業(yè)發(fā)展脈絡：
