汽车车身整体外观设计初步.doc

摘 要 随着汽车工业的发展，汽车更新换代越来越快，消费者对汽车的外形要求越来越多元化，这很大程度上是由车身技术的发展所决定的，所以汽车车身造型是整个汽车制造的重要组成部分。汽车造型设计师科学性和艺术性相结合的一项工作，它涉及到许多领域，包括空气动力学、美学的应用、人机工程学、计算机辅助技术等，对学科的交叉应用十分普遍。 基于对车身造型的爱好，本次论文大体从两个方面来研究车身外形： （1）从理论上分析影响车身造型的因素。经过学习国内外汽车的发展概况，充分了解到，每种车型的出现都是一项新的技术的变革或创新；对于汽车车身现代技术的发展更需要充分研究影响车身造型的因素。本文概述了汽车发动机的布置设计方案对车身外形设计的影响，发动机的布置形式及传动系和外形设计的关系，最后分析了空气动力学和美学在外形设计中的应用。 （2）使用PROE软件对车身模型的模仿设计，主要通过学习三维模型的建立来对车身模型的绘制。在软件的使用中灵活使用各种建立空间曲线、空间曲面的方法以及空间曲面的过渡处理。最后形成三维渲染效果图，创造真实的效果。 关键字：车身造型 空间曲面 渲染 ABSTRACT With the development of the automotive industry, automotive replacement faster and faster, shape requirements for automotive consumers increasingly diversified, which is largely determined by the development of the body, so car styling is an important part of the entire automobile manufacturing. Science and art of combining a car stylists work it relates to many areas, Including the application of aerodynamics, aesthetics, ergonomics, computer-aided technology, on cross-disciplinary applications are very common. Based on the love of styling, this paper generally from two aspects to study body shape. First, from the theoretical analysis of the factors that affect body shape. After learning the overview of the development of domestic and foreign automobiles, fully understand the change of each model are a new technology or innovation; Need to fully study the factors affecting the styling for the development of the modern technology of the auto body ,This article provides an overview of the layout design of the automobile engine body shape design, arrangement and the driveline and the relationship of the exterior design of the engine, Finally, the aerodynamic and aesthetic design in the shape. The second is to use PROE software to mimic the design of the body model, Mainly through the study of 3D model to draw on the body model. Flexible in the use of the software using a variety of the establishment of the transitional treatment of the space curve, space, surface and space surface
