本田系列汽车车身的三维造型设计 摘 要 本文通过应用实例对汽车车身设计新方法进行了探讨，讨论一种并行汽车车身设计方法。应用此方法，对本田轿车车身进行了改型设计，并利用有限元、优化 ，可传统的汽车车身设计方法的整个过程是基于手工设计完成的。分为初步设计与技术设计两个阶段其特点是整个过程是通过实物、模型、图纸、样板等来传递信息，至少进行1:5油泥模型、全尺寸油泥模型和样车制作等阶段，还要进行1:5油泥模型1:1全尺寸油泥模型、实车三次风洞试验；还要进行车身原始数据保留的车身主图板、车身主模型制作。 随着计算机技术的发展,高速图形终端和工作站的出现 ，引进CAD/CAM等现代殴计方法在车身设计中的应用这种方法(传统的车身CAD方法)的一个主要工作是利用计算机辅助几何设计( CAGD) 方法来进行车身几何造型设计，即要在计算机上建立一个车身表面模型以取代传统设计中的三维实体模型 。 关键字：汽车车身；改型设计；油泥模型；表面模型 Honda Series Auto Body Design of Three-Dimensional Modeling Abstract Author: Tutor: Examples of the car body through the application of new methods designed to explore and discuss a parallel car body design. With this method, carried out on modified Honda car body design and finite element, optimization can be a traditional auto body design isbased on the whole process designed to complete the hand. Preliminary design and technology is divided into two stages of the design process is characterized by the kind, or model, plan, model, etc. to convey information, at least 1: 5 clay model, full-size clay model and prototype-production stage: even to 1: 5 clay model, 1: 1 full-size clay model, vehicle three wind tunnel tests; also the raw data for the body to retain the main body drawing board, the main body modeling. With the development of computer technology, high-speed graphics terminals and workstations appear, the introduction of T CAD / C AM hitting account of modern methods of body design in this way (the traditional method of body CAD) of a main task is to use computer-aided geometric design (CAGD) approach to body geometry design, that is, to build a computer model of the body surface to replace the traditional design of three-dimensional solid model.
