ug风扇建模仿真设计说明书.docx

摘要

面对剧烈的市场竞争，制造业必需加速产品开发进程，缩短设计开发周期。计算机技术和计算机图形学的不断进展，为人们供给了强有力的工具，三维CAD/CAM/CAE集成化软件被广泛应用于制造业。与传统的装配设计相比，虚拟装配技术能满足并行工程的要求，实现产品可装配的设计，准时觉察产品设计中的问题，提高装配质量和装配效果。

争论是在UG软件设计平台上完成风扇的三维造型设计。UG软件具有很强大的实体造型、曲面造型、虚拟产品装配仿真、工程图生成等功能。论文论述了风扇虚拟设计中的关键环节，即零部件建模、虚拟装配、动态仿真设计等。并对产品设计中的虚拟设计方法与传统设计方法的差异、优越性进展了比对。通过可视化显示装配、干预分析然后以求到达准确运动仿真，使生产真正在高效、高质量、低本钱的环境下完成。
