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(chē)車(chē)門(mén)行業(yè)概述 如今汽車(chē)產(chǎn)品的更新?lián)Q代速度很快，而每一款汽車(chē)的設(shè)計(jì)作為一個(gè)系統(tǒng)的工程，是相對(duì)獨(dú)立的過(guò)程，很多跨國(guó)汽車(chē)公司早在幾十年前就已經(jīng)打破了這種相對(duì)的獨(dú)立，將設(shè)計(jì)的每一個(gè)過(guò)程凝練提升，形成一個(gè)個(gè)模塊，按照系統(tǒng)的方法組織起來(lái)，定義為汽車(chē)設(shè)計(jì)流程。在以后的新車(chē)設(shè)計(jì)中，將每一個(gè)過(guò)程融入了這種既定的設(shè)計(jì)模式，按部就班地推進(jìn)，控制著汽車(chē)的每一個(gè)非常詳細(xì)的設(shè)計(jì)過(guò)程，從而順利高效地完成設(shè)計(jì)。在國(guó)內(nèi)，一汽、二汽、上汽等大的汽車(chē)企業(yè)集團(tuán)都已經(jīng)建立起了比較完善的產(chǎn)品設(shè)計(jì)流程，在國(guó)內(nèi)愈演愈烈的汽車(chē)產(chǎn)品競(jìng)爭(zhēng)中，這些企業(yè)的產(chǎn)品競(jìng)爭(zhēng)力有著明顯的優(yōu)勢(shì)，產(chǎn)品更新速度快，質(zhì)量可靠，深得用戶(hù)的信賴(lài)，可見(jiàn)研發(fā)流程的建立對(duì)企業(yè)的重要意義。 伴隨著汽車(chē)車(chē)身造型的設(shè)計(jì)與修改要求日趨增高，參數(shù)化設(shè)計(jì)更符合和貼近現(xiàn)代CAD中的概念設(shè)計(jì)和并行設(shè)計(jì)思想，并可提高設(shè)計(jì)與分析的柔性，因此車(chē)身模型的參數(shù)化設(shè)計(jì)經(jīng)成為車(chē)輛制造行業(yè)發(fā)展的必然趨勢(shì)。參數(shù)化設(shè)計(jì)是以一種全新的思維方式來(lái)進(jìn)行產(chǎn)品的創(chuàng)和修改設(shè)計(jì)的方法。目前傳統(tǒng)的手工造型方法已被建立在各種先進(jìn)的造型建模軟件基礎(chǔ)上的計(jì)算機(jī)輔助造型方法所取代，參數(shù)化設(shè)計(jì)技術(shù)能夠快速吸收國(guó)外汽車(chē)車(chē)身設(shè)計(jì)的先進(jìn)技術(shù)，快速響應(yīng)市場(chǎng)，提高我國(guó)自主設(shè)計(jì)開(kāi)發(fā)汽車(chē)的能力，提高汽車(chē)產(chǎn)品競(jìng)爭(zhēng)能力。 隨著汽車(chē)技術(shù)的發(fā)展，汽車(chē)的舒適性不斷提高以滿(mǎn)足人們的要求。汽車(chē)車(chē)門(mén)是車(chē)上相對(duì)獨(dú)立的總成，車(chē)門(mén)設(shè)計(jì)不但關(guān)系到汽車(chē)的實(shí)用性，對(duì)汽車(chē)也有很大的裝飾作用。因此車(chē)門(mén)的設(shè)計(jì)也越來(lái)越講究，而且使用越來(lái)越多的網(wǎng)絡(luò)和電控技術(shù)。從1957年新中國(guó)的第一輛汽車(chē)正式生產(chǎn)下線(xiàn)，中國(guó)汽車(chē)在20世紀(jì)中期經(jīng)歷了漫長(zhǎng)的緩慢發(fā)展階段，在經(jīng)過(guò)2003年和2006年的兩輪爆發(fā)式增長(zhǎng)后，開(kāi)始步入平穩(wěn)增長(zhǎng)階段。2009年嚴(yán)峻的宏觀經(jīng)濟(jì)形勢(shì)下，中國(guó)汽車(chē)行業(yè)的發(fā)展面臨著前所未有的挑戰(zhàn)與機(jī)遇，同時(shí)也受到來(lái)自各個(gè)方面的沖擊。中國(guó)要想從汽車(chē)制造大國(guó)發(fā)展成為汽車(chē)產(chǎn)業(yè)強(qiáng)國(guó)，就必須在汽車(chē)產(chǎn)品的研發(fā)上取得突破。歐美日的汽車(chē)企業(yè)之所以能夠如此強(qiáng)勢(shì)，與他們幾十年甚至上百年的技術(shù)革新與經(jīng)驗(yàn)積累是分不開(kāi)的，翻開(kāi)他們汽車(chē)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(luò)：明確的市場(chǎng)定位，堅(jiān)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(chē)產(chǎn)業(yè)作為中國(guó)經(jīng)濟(jì)的支柱產(chǎn)業(yè)之一，近年來(lái)在技術(shù)研發(fā)上的投入力度明顯增加，從過(guò)去的汽車(chē)產(chǎn)品進(jìn)口到產(chǎn)品引進(jìn)生產(chǎn)再到技術(shù)轉(zhuǎn)化，近幾年來(lái)更是直接的技術(shù)引進(jìn)、并購(gòu)國(guó)外先進(jìn)的汽車(chē)企業(yè)，中國(guó)的汽車(chē)技術(shù)如雨后春筍般迅猛發(fā)展。 車(chē)門(mén)是整個(gè)車(chē)身中結(jié)構(gòu)復(fù)雜又相對(duì)獨(dú)立的一個(gè)總成,它主要由車(chē)門(mén)骨架及蓋板、車(chē)門(mén)護(hù)面、門(mén)窗、車(chē)門(mén)玻璃及玻璃升降器、門(mén)鎖及其手柄、車(chē)門(mén)鉸鏈、車(chē)門(mén)密封條和車(chē)門(mén)開(kāi)關(guān)機(jī)構(gòu)組成。車(chē)門(mén)是汽車(chē)車(chē)身設(shè)計(jì)中的一個(gè)相對(duì)獨(dú)立的零部件。在車(chē)門(mén)設(shè)計(jì)中其安全性尤為重要，它必須保證在車(chē)輛發(fā)生碰撞時(shí)，盡可能地減少對(duì)行人和乘員造成的傷害，因此必須要求車(chē)門(mén)外覆蓋件表面光潔、有韌性；門(mén)鎖、門(mén)鉸鏈以及車(chē)門(mén)門(mén)體必須能夠按照A柱一B柱一C柱的路線(xiàn)傳遞碰撞沖擊力；碰撞后的車(chē)門(mén)必須能夠輕松地不借助于任何輔助工具用手打開(kāi)。鑒于側(cè)面碰撞對(duì)乘員造成的危險(xiǎn)性，在設(shè)計(jì)車(chē)門(mén)時(shí)注意將車(chē)門(mén)的變形限制在一定范圍內(nèi)，為乘員提供一個(gè)有效的生存空間。這些都要求車(chē)門(mén)必須具備足夠的強(qiáng)度和剛度。在汽車(chē)車(chē)身設(shè)計(jì)的過(guò)程中，車(chē)門(mén)總成的布置設(shè)計(jì)除與整體設(shè)計(jì)有著協(xié)調(diào)配合關(guān)系外，可稱(chēng)的上是一個(gè)相對(duì)獨(dú)立的，最具有代表性的車(chē)身總成設(shè)計(jì)。它不僅要與整車(chē)造型協(xié)調(diào)一致，還要保證必要的開(kāi)度，方便上下車(chē)，良好的安全性，穩(wěn)定的操縱性，密封性，工藝性，足夠的強(qiáng)度剛度，以滿(mǎn)足功能上的要求。因此車(chē)門(mén)的設(shè)計(jì)成為車(chē)身設(shè)計(jì)中的一個(gè)重要環(huán)節(jié)。 生產(chǎn)廠家為了能在市場(chǎng)競(jìng)爭(zhēng)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(kāi)發(fā)周期，提高勞動(dòng)生產(chǎn)率，所有這些迫使設(shè)計(jì)者不斷地尋求智能化的設(shè)計(jì)工具和先進(jìn)的設(shè)計(jì)方法。本課題的研究?jī)?nèi)容就是在這樣的情況下產(chǎn)生的。
