摘 要
車門是車身結(jié)構(gòu)中一個重要而復(fù)雜的總成，熟悉車門結(jié)構(gòu)的功能要求、結(jié)構(gòu)特點和較見的結(jié)構(gòu)處理方法是車門結(jié)構(gòu)設(shè)計的基礎(chǔ)；另外，在具體的結(jié)構(gòu)設(shè)計過程中，正確的方法、步驟是實現(xiàn)合理設(shè)計的關(guān)鍵，如車門總體結(jié)構(gòu)的確定、附件的布置及運動校核、結(jié)構(gòu)的統(tǒng)一協(xié)調(diào)和強度、剛度、可靠性等方面都有一定的規(guī)律和要求。
轎車門由門外板、門內(nèi)板、門窗框、門玻璃導(dǎo)槽、門鉸鏈、門鎖及門窗附件等組成。內(nèi)板裝有玻璃升降器、門鎖等附件，為了裝配牢固，內(nèi)板局部還要加強。為了增強安全性，外板內(nèi)側(cè)一般安裝了防撞桿。內(nèi)板與外板通過翻邊、粘合、滾焊等方式結(jié)合，針對承受力不同，要求外板質(zhì)量輕而內(nèi)板剛性要強，能夠承受較大的沖擊力。
通過對國內(nèi)外車身技術(shù)的發(fā)展趨勢的回顧與理解，我們用現(xiàn)代計算機技術(shù)與國外先進(jìn)的流程化設(shè)計思想，對車門基本結(jié)構(gòu)與組成進(jìn)行相關(guān)分析；然后我們對車門的開發(fā)流程進(jìn)行了相關(guān)研究。

ABSTRACT
Car body door is an important assembly of complexity in the body structure.Structural function requirement,specialty of structure and general handling method of structure are the basis of body door structure design.In the course of door structural design,correct method and procedure are the key points to realize rational design,such as determination of door structure outlay,arrangement of accessories,motion verification and also others as overall coordination of structure,strength,rigidity,reliability etc.,all have definite rule and demand.
Car body door is composed of such as outer panel,inner panel,window frames,door glass guide slot,hinges,lock and door components accessories.The inner panel with regulator,locks and other accessories,is also necessary to strengthen local boards in order to assemble solidly.In order to enhance the safety of the door installed door beam in general. Outer panel and inner panel combine with the flange plate,bonding,roll welding.For different requirements,the quality of light outer panel and rigid strong inner panel,can withstand a greater impact.
Technology at home and abroad through the development trend of the body of the review and understanding,we do the analysis on the basic structure and the component using the modern computer technology and advanced design concepts of the process.And we carried out relevant research on the door development process.
