摘 要
    6110型双层客车车身造型相当重要, 它直接影响整车的视觉效果。文章简要介绍我国客车造型的发展和现状; 较详细说明客车整体、局部造型及内饰技术和在造型中应注意的一些问题, 并展望我国客车造型未来的新局面。
    6110型双层客车车身设计是设计过程中非常重要得一个环节。车身根据其承载形式可分为承载式，非承载式和半承载式。按结构划分，整个骨架分为前围、后围、左侧侧围和顶盖五大部分。
    本次毕业设计主要采用auto CAD软件设计发动机后置的城市中型客车车身骨架的设计过程。文章主要阐述了车身骨架设计原则及依据，介绍了各种车身骨架结构形式，给出了车身骨架设计过程结构与尺寸，并对车身骨架进行了车身骨架的受载分析和强度分析，论了车身骨架的制造工艺.为了满足车身强度要求，车身骨架采用CO₂气体保护焊焊接。

ABSTRACT
 
     The importance of busmodeling directly influences the bus vision . Th is article briefly introduces Ch inese busmodeling development and p resent situation,more detailedly describes the w hole and partial area modeling, trim tech2nology and some questions needing attention. It also look s forw ard to the future new situation of Ch inese busmodel2ing.
The 6110body design is an automobile design process Central Africa constant weight fine link.The automobile body acts according to its load bearing form to be possible to divide into the load bearing type, non-load bearing type and half load bearing type. the side encircles with the roof panel five major parts.
Mainly I use auto for this graduation project the CAD software design engine postpositioned city medium passenger train body frame the design process.The article mainly elaborated the body frame principle of design and the basis.Introduced each kind of body frame structural style, has given the body frame design process structure and the size, and carried on the body frame to the body frame to carry the analysis and the intensity analysis, elaborated the body frame manufacture craft.In order to satisfy the skeleton the intensity request, the entire body frame uses the CO2 shielded welding welding.
