本科生畢業(yè)設計(論文) I 摘 要 隨著汽車行業(yè)的蓬勃發(fā)展,以及人機工程學、空氣動力學在汽車上的應用,車身總布置也在飛速的變革與發(fā)展。 車身總布置設計是經(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、空氣動力學和現(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)新藝術風格的有機 結(jié)合也影響著車身總布置的美學實踐。然而, 每一款新車型的問世都離不開車身總布置和它的設計工具, 汽車車身總布置是汽車概念設計階段的一項相當重要的方案設計工作。 本次設計主要內(nèi)容是根據(jù)人機工程學的理論和在汽車上實際應用的分析,進行總布置設計。 本文介紹汽車總布置設計工具人體模型,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 關鍵詞: 車身 總布置設計; 人機工程學; 人體模型;眼橢圓。 本科生畢業(yè)設計(論文) II 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. 本科生畢業(yè)設計(論文) III 目 錄 第 1 章 緒 論 ........................................................................................................... 1 車身總布置設計概述 ................................................................................ 1 本設計采用的繪圖軟件介紹 ..................................................................... 2 CATIA 簡介 ..................................................................................... 2 CATIA 的功能特點 ........................................................................ 3 CATIA 軟件發(fā)展 ............................................................................. 4 CATIA 人機工程功能在產(chǎn)品設計中的應用 ................................. 4 研究本課題的意義 ............................................................................. 7 畢業(yè)設計內(nèi)容 ..................................................................................... 8 第 2 章 車身設計方法 ............................................................................................. 9 傳統(tǒng)的車身設計方法 ................................................................................. 9 現(xiàn)代設計方法 ............................................................................................ 9 整車布置的基準線 —— 零線的確定 ...................................................... 10 本設計采用的設計方法 .......................................................................... 12 概念設計 ....................................................................................... 12 工程設計 ....................................................................................... 12 車身總布置內(nèi)容及原則 .......................................................................... 12 車身承載方式的確定 ....................................................................... 13 車身承載方式 ................................................................................ 13 本車承載方式的確定 ............................................................................... 15 第 3 章 人機工程學的基礎研究 ........................................................................... 16 人機工程學概況 ...................................................................................... 16 人機工程學簡介 ....................................................................................... 18 人機系統(tǒng)概述 ........................................................................................... 20 不同人種間的人體模型差異 ................................................................... 21 我國人體尺寸標準 ................................................................................... 22 人體的主要尺寸 ............................................................................ 23 立姿人體尺寸 ................................................................................ 24 坐姿人體尺寸 ................................................................................ 25 人體水平尺寸 ................................................................................ 27 SAE 人體模型 .......................................................................................... 28 本科生畢業(yè)設計(論文) IV 結(jié)論 .......................................................................................................... 29 第 4 章 轎車車身總布置 ....................................................................................... 30 人體功能尺寸 ........................................................................................... 30 人體模板關節(jié)角度的調(diào)節(jié)范圍 ............................................................... 34 座椅的布置 ..........
