【正文】 suppliers。 Tong platform automotive products often have similar, patibility, versatilityand modular. Automotive products platform Want to have a living core automotive products, the product platform and the primary application platform products derived from core products, resulting in the core product based on the platform of products subdivided to upgrade products and derivative products, upgrades are based on the further improvement of the original core products。 derivatives alienation derivative on the basis of the original core products to meet different market segments products.The life cycle of the vehicle platforms Hexi value of the life cycle of the platform. Continuous spiral of development for the platform, the platform39。s core products, upgrades, derivative products must extend its life cycle, and continue to increase its contribution to the whole platform, core products based on the gradual increase in derivative products to meet more scenes market demand for our products, to expand the value of the platform in the space dimension, covering more market children derivative products according to market demand to exit the upgrade products to meet the everincreasing function of the scenes market users or performance requirements to ensure that the platform petitiveness in the market of scenes.Need to create a virtuous cycle of the platform development model of the system, given the characteristics of the product, the general connotation of automotive products platform includes four aspects: technology and management subplatform. This section includes all mon technology platform products, the core technology and product line and brand, is a concrete manifestation of the value of the platform。 structure and function of subplatform, the platform did not praise words, general performance。 does not appear in the material, to the greatest limit of quiver platform, the procurement system based on the same information u manufacturing subplatform design, manufacturing resource sharing, reduce the cost of product development, manufacturing, organic bination of the words above platform car platform life cycle the key of the development model.Platform life cycle of its product life cycle decided to upgrade the product life cycle determines the the platform lifecycle longitudinal time, and derivative products, decided to expand its transverse spatial coverage, product design objective decisionmaking when the product life and go from the beginning, the development ofthe direction of scientific and rational design goals of its design guidelines, in order to overe the arbitrariness and plexity of product design, to ensure the quality of product design, while making the cost of the product, service, environment and other goals.Platform life cycle of its product life cycle decided to upgrade the product life cycle determines the the platform lifecycle longitudinal time, and derivative products, decided to expand its transverse spatial coverage, product design objective decisionmaking when the product life and go from the beginning, the development ofthe direction of scientific and rational design goals of its design guidelines, in order to overe the arbitrariness and plexity of product design, to ensure the quality of product design, while making the cost of the product, service, environment and other goals.汽車產(chǎn)品平臺生命周期循環(huán)發(fā)展模式 20世紀初，汽車實現(xiàn)大批量流水線作業(yè)，亨利福特使用平臺概念，按照功能對汽車進行自系統(tǒng)分類，探討意在提高汽車的書異性，易實用性，耐用性的技術。在我國汽車產(chǎn)業(yè)快速發(fā)展，汽車制造企業(yè)廣泛采用產(chǎn)品平臺技術的同時，出現(xiàn)一些困擾產(chǎn)品平臺持續(xù)發(fā)展的問題，如在開發(fā)過程中汽車產(chǎn)品如何以高質(zhì)量高效率低成本地滿足安全、環(huán)保、節(jié)能的要求；基于通用平臺，車型如何滿足顧客多層系的需求，如何在平臺中引入先進的技術以提升產(chǎn)品的核心競爭力等。 汽車產(chǎn)品有其特殊性，具體表現(xiàn)為：汽車殘品擁有多項共性技術；汽車產(chǎn)品零部件數(shù)目較大，依托眾多的零部件供應商；佟平臺汽車產(chǎn)品通常具有相似性、兼容性、通用性和模塊化。汽車產(chǎn)品平臺旺旺擁有一個活多個核心汽車產(chǎn)品，是產(chǎn)品平臺的基本以及首要應用，其他平臺產(chǎn)品由核心產(chǎn)品衍生出來，由此在核心產(chǎn)品基礎上，可將平臺的產(chǎn)品再細分為升級產(chǎn)品與衍生產(chǎn)品，升級產(chǎn)品是基于原有核心產(chǎn)品的進一步改進；衍生產(chǎn)品是指在原有核心產(chǎn)品的基礎上異化衍生，滿足不同細分市場的產(chǎn)品。 汽車平臺生命和周期其河西是平臺價值的生命周期。為使平臺不斷循環(huán)上升發(fā)展，其平臺的核心產(chǎn)品、升級產(chǎn)品、衍生產(chǎn)品必須延長生命周期，并不斷增加其對整個平臺的貢獻，在核心產(chǎn)品的基礎上逐步增加衍生產(chǎn)品可以滿足更多的戲份市場的產(chǎn)品需求，以擴大平臺在空間維度的價值，涵蓋更多的市場，兒各個衍生產(chǎn)品不斷根據(jù)市場需求退出升級產(chǎn)品以滿足該戲份市場用戶不斷增加的功能或者性能上的需求，以保證平臺在戲份市場的競爭力。 為實現(xiàn)平臺的良性循環(huán)需要建立系統(tǒng)的發(fā)展模型，鑒于產(chǎn)品的特性，概括汽車產(chǎn)品平臺內(nèi)涵包括四個方面：技術與管理子平臺。該部分包括所有平臺產(chǎn)品的共性技術、核心技術以及產(chǎn)品線與品牌等，是平臺價值的具體表現(xiàn)；結構與功能子平臺，是平臺產(chǎn)品沒夸話、通用化的表現(xiàn)；不見于材料、能夠最大限度的箭筒平臺產(chǎn)品，基于同一的采購體系，信息u制造子平臺，實現(xiàn)設計、制造資源的共享，降低產(chǎn)品開發(fā)制造成本，將以上四個字平臺的內(nèi)容有機結合是建立汽車平臺生命周期循環(huán)發(fā)展模式的關鍵。 平臺生命周期由其產(chǎn)品的生命周期決定，升級產(chǎn)品的生命周期決定平臺生命周期的縱向時間，而衍生產(chǎn)品則決定其橫向空間覆蓋的拓展，產(chǎn)品設計目標決策時產(chǎn)品生命和走起的開端，制定科學合理的產(chǎn)品設計目標其指引設計的方向，從而克服產(chǎn)品設計工作中的隨意性和復雜性，保證產(chǎn)品設計質(zhì)量，同時使產(chǎn)品的成本、時間、服務、環(huán)境等目標的實現(xiàn)。汽車產(chǎn)品開發(fā)過程復雜，專業(yè)性較強，工程人員設計的過程是將產(chǎn)品目標分解為部件要求的過程，在了解設計的環(huán)境因素，綜合顧客的各方面你的需求，并且掌握技術發(fā)展與政策環(huán)境的前提下，制定合理的產(chǎn)品時間、質(zhì)量、成本、服務、環(huán)境目標。根據(jù)產(chǎn)品的總體目標，按質(zhì)量功能展開模型展開到各總成，所有低階別的目標能夠保證高級別目標的實現(xiàn)，而高級別目標 則有相應的低級別目標支撐，設計目標在質(zhì)量功能展開后，可獲得各總成區(qū)域的細化技術指標，從而知道區(qū)域工程師進行工程設計。致謝本篇論文是在王善利老師的精心指導下完成的，從選題到資料搜集，到寫作修改，到論問修改都給予了精心的指導和耐心的幫助，無論從學術水平還是學術造詣上都使我受益非淺。在網(wǎng)站的設計中，親身經(jīng)歷了從學習、研究到社會實踐的過程。同時我還要感謝在我學習期間給我極大關心和支持的各位老師以及關心我的同學。通過這段時間的努力，網(wǎng)站終于完成，雖然耗費了許多經(jīng)歷和時間，但是它驗證了我的知識和能力，讓我有了不斷提高自身素質(zhì)的意識。網(wǎng)站的開發(fā)讓我對書本上的知識點和理論有了更深一層的了解，使我學會了如何利用所學的知識,把理論結合于實踐中,進而對本專業(yè)有了更進一步的認識。此后,我會加倍努力的去研究,在熟練的基礎上掌握更多的新型技術,來提高自己的開發(fā)水平。最后再一次感謝在畢業(yè)設計中曾經(jīng)幫助過我的所有老師和同學，謝謝你們在我學習期間給我極大的關心和支持。
