摘 要

电风扇是一种常见的家用电器,本次设计以台式电风扇为例,来详细讲述Pro/E设计电风扇的全过程。其外型结构较为复杂,如果用传统的CAD绘图软件设计非常困难,Pro/E可以轻松解决这个问题,Pro/E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。本文主要讲述电风扇外形实体建模、电风扇的组件装配、电风扇的叶片的转动仿真。设计综合运用了拉伸、扫描、混合等实体建模的基本方法;曲面修剪、合并、偏移、实体化等复杂的建模方法;装配的的设计方法用到了无连接口的约束和有连接口的约束。在电风扇的建模设计总体上是采用了自底向上的设计方法,在组件在设计过程中也采用了自顶向下的设计方法。我们在学习电风扇的建模设计过程中,除了学习建模方法外,更重要的是学习这种模型设计思想。

关键词:电风扇、Pro/E、实体建模、装配、运动仿真

Abstract

Electric fan is a common household appliances, this design to desktop electric fan, for example, to expound Pro/E design fan process. Its exterior structure is relatively complex, if use the traditional CAD drawing software design is very difficult, Pro/E can be easy to solve this problem, Pro/E software has very powerful entities modelling, surface modeling, virtual assembling simulation, engineering drawing generation, and other functions. This article mainly described entity modeling, electric fan shape of component assembly, electric fan blade rotation simulation. Design comprehensive use the tensile, scanning, mixing entity modeling the basic method, Surface trim, merger, offset, substantiate complex modeling method, Assembly design method used with a mouth of nonartesian-artesian constraints and connection mouth constraints. The fan modeling design was generally adopted a bottom upward design methods, in the component in the design process also USES a top-down design method. We are studying the fanner modeling design process, besides study modeling method outside, more important is to learn this model design thought.
