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(shè)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(shè)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(shè)計流程。在以后的新車設(shè)計中，將每一個過程融入了這種既定的設(shè)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(shè)計過程，從而順利高效地完成設(shè)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(shè)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(shè)計與修改要求日趨增高，參數(shù)化設(shè)計更符合和貼近現(xiàn)代CAD中的概念設(shè)計和并行設(shè)計思想，并可提高設(shè)計與分析的柔性，因此車身模型的參數(shù)化設(shè)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(shè)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(shè)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(chǔ)上的計算機輔助造型方法所取代，參數(shù)化設(shè)計技術(shù)能夠快速吸收國外汽車車身設(shè)計的先進技術(shù)，快速響應市場，提高我國自主設(shè)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(shù)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(shè)計不但關(guān)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(shè)計也越來越講究，而且使用越來越多的網(wǎng)絡和電控技術(shù)。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(shù)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：明確的市場定位，堅定不移的技術(shù)研發(fā)，引領(lǐng)潮流的戰(zhàn)略方向，這一切，做足了他們的原始積累。我們的起步盡管有些晚，但是汽車產(chǎn)業(yè)作為中國經(jīng)濟的支柱產(chǎn)業(yè)之一，近年來在技術(shù)研發(fā)上的投入力度明顯增加，從過去的汽車產(chǎn)品進口到產(chǎn)品引進生產(chǎn)再到技術(shù)轉(zhuǎn)化，近幾年來更是直接的技術(shù)引進、并購國外先進的汽車企業(yè)，中國的汽車技術(shù)如雨后春筍般迅猛發(fā)展。 車門是整個車身中結(jié)構(gòu)復雜又相對獨立的一個總成,它主要由車門骨架及蓋板、車門護面、門窗、車門玻璃及玻璃升降器、門鎖及其手柄、車門鉸鏈、車門密封條和車門開關(guān)機構(gòu)組成。車門是汽車車身設(shè)計中的一個相對獨立的零部件。在車門設(shè)計中其安全性尤為重要，它必須保證在車輛發(fā)生碰撞時，盡可能地減少對行人和乘員造成的傷害，因此必須要求車門外覆蓋件表面光潔、有韌性；門鎖、門鉸鏈以及車門門體必須能夠按照A柱一B柱一C柱的路線傳遞碰撞沖擊力；碰撞后的車門必須能夠輕松地不借助于任何輔助工具用手打開。鑒于側(cè)面碰撞對乘員造成的危險性，在設(shè)計車門時注意將車門的變形限制在一定范圍內(nèi)，為乘員提供一個有效的生存空間。這些都要求車門必須具備足夠的強度和剛度。在汽車車身設(shè)計的過程中，車門總成的布置設(shè)計除與整體設(shè)計有著協(xié)調(diào)配合關(guān)系外，可稱的上是一個相對獨立的，最具有代表性的車身總成設(shè)計。它不僅要與整車造型協(xié)調(diào)一致，還要保證必要的開度，方便上下車，良好的安全性，穩(wěn)定的操縱性，密封性，工藝性，足夠的強度剛度，以滿足功能上的要求。因此車門的設(shè)計成為車身設(shè)計中的一個重要環(huán)節(jié)。 生產(chǎn)廠家為了能在市場競爭中立于不敗之地，就必須提高產(chǎn)品質(zhì)量，降低生產(chǎn)成本，縮短產(chǎn)品的開發(fā)周期，提高勞動生產(chǎn)率，所有這些迫使設(shè)計者不斷地尋求智能化的設(shè)計工具和先進的設(shè)計方法。本課題的研究內(nèi)容就是在這樣的情況下產(chǎn)生的。
