【正文】 本科生畢業(yè)設(shè)計（論文） 摘 要 隨著汽車行業(yè)的蓬勃發(fā)展，以及人機工程學(xué)、空氣動力學(xué)在汽車上的應(yīng)用，車身總布置也在飛速的變革與發(fā)展。 車身總布置設(shè)計是經(jīng)驗和原理方法的結(jié)合，是在考慮整車形式、車身與底盤的關(guān)系、以及總布置和造型傳遞給車身內(nèi)部布置的一些約束條件下，進行車室內(nèi)部布置，是基于功能和約束的方案尋求最優(yōu)的過程。一個與眾不同的駕駛空間：開闊的視野，舒適的座椅布置，布置緊湊的儀表以及伸手可及的操作元件，能給人充分的心理滿足和安全感。 人機工程學(xué)、空氣動力學(xué)和現(xiàn)代化制造方法的發(fā)展促使汽車車身總布置的不斷更新和完善，傳統(tǒng)與創(chuàng)新藝術(shù)風(fēng)格的有機 結(jié)合也影響著車身總布置的美學(xué)實踐。然而， 每一款新車型的問世都離不開車身總布置和它的設(shè)計工具， 汽車車身總布置是汽車概念設(shè)計階段的一項相當(dāng)重要的方案設(shè)計工作。 本次設(shè)計主要內(nèi)容是根據(jù)人機工程學(xué)的理論和在汽車上實際應(yīng)用的分析，進行總布置設(shè)計。 本文介紹汽車總布置設(shè)計工具人體模型，眼橢圓。 提出了綜合考慮駕駛員舒適性、視野性、腿部操縱空間、方向盤、頂蓋等因素的 H 點區(qū)域法。利用 CATIA進行總布置設(shè)計 ,CATIA對于提高車身總布置的質(zhì)量，以及縮短產(chǎn)品開發(fā)周期具有非常大的現(xiàn)實意義 關(guān)鍵詞： 車身 總布置設(shè)計； 人機工程學(xué)； 人體模型；眼橢圓。 本科生畢業(yè)設(shè)計（論文） I Abstract With the vigorous development of auto industry, and ergonomics, air dynamics in automotive applications, general arrangement in the rapid development and reform. Body: the layout design experience and the principle of method is bined, is considering vehicle body and forms, the chassis layout, and transfer to body shape and some internal layout constraints on car interior ministry decorate, it is based on the function and constraints for the solution of the optimal process. A special driving space: open vision, fortable seats arrangement of instrumentation and arrangement, pact and operating ponents, can give a person to fully satisfy the psychology and security. the modern automobile body is always arranging also in the rapid transformation and the manmachine engineering, the aerodynamics and the modernized manufacture method development urges the unceasing renewal and the consummation which the automobile body always arranges, traditional and the innovation artistic style anic synthesis is also affecting esthetics practice which the automobile body always , each section new vehicle being published cannot leave the automobile body always to arrange and its design tool, the automobile body total arrangement is an automobile conceptual design stage quite important project design work. The main content of the theory is based on ergonomics in cars and practical application analysis, the layout design. Introduces the layout design tool car body model, elliptic. Puts forward prehensive consideration of the pilot, leg vision fortableness, manipulation of space, the steering wheel, the above factors zone method H. To improve the CATIA layout of quality, body and shorten the development cycle has very great practical significance Keywords: body layout design, Ergonomics, Human model, Eye ellipse. 目 錄 本科生畢業(yè)設(shè)計（論文） II 第 1 章 緒 論 ............................................................................................................... 0 車身總布置設(shè)計概述 ......................................................................................... 0 本設(shè)計采用的繪圖軟件介紹 .............................................................................. 1 CATIA 簡介 ................................................................................................... 1 CATIA 的功能特點 ...................................................................................... 2 CATIA 軟件發(fā)展 ........................................................................................... 3 CATIA 人機工程功能在產(chǎn)品設(shè)計中的應(yīng)用 ............................................... 3 研究本課題的意義 .......................................................................................... 6 畢業(yè)設(shè)計內(nèi)容 .................................................................................................. 7 第 2 章 車身設(shè)計方法 ................................................................................................. 8 傳統(tǒng)的車身設(shè)計方法 .......................................................................................... 8 現(xiàn)代設(shè)計方法 ..................................................................................................... 8 整車布置的基準(zhǔn)線 —— 零線的確定 ................................................................. 9 本設(shè)計采用的設(shè)計方法 ................................................................................... 11 概念設(shè)計 .................................................................................................... 11 工程設(shè)計 .................................................................................................... 11 車身總布置內(nèi)容及原則 ................................................................................... 11 車身承載方式的確定 .................................................................................... 12 車身承載方式 ............................................................................................. 12 本車承載方式的確定 ........................................................................................ 14 第 3 章 人機工程學(xué)的基礎(chǔ)研究 ............................................................................... 15 人機工程學(xué)概況 ............................................................................................... 15 人機工程學(xué)簡介 ................................................................................................ 17 人機系統(tǒng)概述 .................................................................................................... 19 不同人種間的人體模型差異 ............................................................................ 20 我國人體尺寸標(biāo)準(zhǔn) ............................................................................................ 21 人體的主要尺寸 ......................................................................................... 22 立姿人體尺寸 ............................................................................................. 22 坐姿人體尺寸 ............................................................................................. 24 人體水平尺寸 ............................................................................................. 26 SAE 人體模型 ................................................................................................... 27 結(jié)論 ....................................................................................................
