化要求的前提下，作為汽車三大總成之一的車身，已經(jīng)后來居上越來越處于主導(dǎo)地位。 關(guān)鍵詞： 車身 總布置 設(shè)計 ； 人機工程學 。 設(shè)計此款公交車的目的是 初步定位市區(qū)主干道的客運市場上 。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)計階段的一項相當重要的方案設(shè)計工作 。 本科生畢業(yè)設(shè)計（論文） I 摘 要 伴隨著社會科技的不斷前進，現(xiàn)代汽車車身總布置也在迅速變革與發(fā)展。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(shù)風格的有機結(jié)合也影響著車身總布置的美學實踐。 本文介紹了某大型低地板城市客車總布置設(shè)計，詳細敘述了總布置方案 設(shè)計的全過程，特別是利用人體工程學進行了駕駛員和乘客的位置確定， 使 駕駛員 及乘客座椅等車內(nèi)設(shè)施符合人機工程學，保證駕駛員 和乘客有安全、舒適的 乘坐 環(huán)境 。以其優(yōu)勢競爭市區(qū)主干道客運市場，并占領(lǐng)一定的市場份額。城市公交車 本科生畢業(yè)設(shè)計（論文） II Abstract Follows the social science and technology unceasing advance, 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. This paper has referred the packaging design of the largescale, low floor city bus, and introduced the whole process of packaging scheme design in detail, especially utilizing the Ergonomics to design the position of the drivers and passengers, Facilities accords with manmachine engineering , ensures that the pilot and the passenger have safe , fortable riding in within making the pilot and the passenger seat wait for a bus environment. The downtown area turnpike road passenger transport marketplace designing that this money public transit vehicle purpose is that the first step fixes position is upper. And the marketplace peting for downtown area turnpike road passenger transport with whose advantage, captures certain market share. Key
