管壳式换热器三维自动化设计及软件开发

Automatic Three Dimensional Design for Tube-Shell Heat Exchanger and Software Development

摘要: 利用Visual Basic对Solid Edge进行二次开发，实现了管壳式换热器三维自动化设计，并编写了相应的设计软件。软件采用模块化设计思想，主要分为工艺计算和三维图形输出两部分。工艺计算可实现管壳式换热器的热力计算和压降计算；三维图形是基于ActiveX Automation技术先采用参数化建模生成独立零件再由自底向上装配的方法生成。软件界面友好，人机交互能力强，能快速生成三维模型，有效提高了设计速度和设计质量。

Abstract: Using Visual Basic to redevelop the Solid Edge, a software is developed to implement automatic three di- mensional drawing of tube-shell heat exchangers. According to the concept of modularization the software is divided into two parts: technical calculation and three dimensional drawing. The thermal calculations and the pressure drop calculations can be finished by the software; Based on the ActiveX Automation technology, using parametric modeling to generate the independent parts and then to generate three-dimensional drawing is output with bottom-up assembly method. At the same time, this software has friendly interfaces and a human-computer interaction environment. It will be benefit to the development of the three dimensional modeling, which can improve the design speed and design qual- ity.
