Based on idea of top-down design using Pro/Engineer, it introduces the configuration design of the product. The design process includes the transmission of the parameter date to the son assemblage and the parts in turn. This method realizes the parameter design of the entirely product. Considered the application of the man-machine project in the motorcycle’s structural design, and defers to the security standard and the standard request of the motorcycle product design, to carry on the design on the motorcycle’s modeling, color, material, as well as the structure. After the product modeling design completed, uses the rendering function of Pro/Engineer to carry on the rendering for the three dimensional modeling. According to function demand to change the high-rise structural model, driving the change of parts by revising parameters, the parameterization design basing on characteristic provides a method for the alterability and concept design of the product model. Abiding by the design intention to change the model, generating series of products and improving design efficiency. Key words：Pro/Engineer；Motorcycle；Structural Design；Top-down design 目 录 1 绪论 3 1.1摩托车的起源 3 1.2摩托车的发展趋势 4 1.3课题目的和意义 5 1.4课题基本要求 6 1.5本章小结 6 2工业造型在产品设计中的应用 7 2.1工业造型设计的概念及特征 7 2.2工业造型设计的方法及其应用 7 2.3摩托车造型设计基本流程 7 2.4三维建模软件的选择 8 2.5本章小结 10 3 摩托车的人机分析与设计 11 3.1 车座的分析与设计 11 3.2摩托车的把手 12 4 摩托车车架的结构与设计 13 4.1摩托车车架结构 13 4.2车架工作载荷 13 4.3自行车造型色彩分析 14 4.5本章小结 14 5 摩托车的发动机机构设计 15 5.1 发动机原理 15 5.2摩托车发动机设计结构参数 15 5.3 本章小结 15 6 建模设计步骤 16 6.1主要零件建模 16 6.1.1车轮建模设计步骤 16 6.1.2 车身建模设计步骤 16 6.2产品装配 18 6.2.1 摩托车的装配 19 6.3产品渲染 20 6.4本章小结 20 7 本文总
