【摘要】 塔设备CAD(TCAD)是属于传统产业与信息技术相结合的课题。CAD技术经过多年的推广已广泛应用于各行各业，实践证明CAD技术的应用大大地提高了设计者的设计效率。但在总体上，压力容器CAD一直落后于其它行业CAD，这是由于压力容器的特殊性造成的。塔设备是化学工业、石油工业以及其它行业中广泛使用的一种化工设备，对整个工厂的投资和运行效率均有重要影响，塔设备的设计一直备受重视。因此开发一套完整的塔器CAD系统是十分必要的。 本文针对塔器CAD的功能需求、系统分析、系统设计、系统实现等问题进行了探讨。通过对塔设备CAD系统进行面向对象分析，利用OMT方法，建立了系统的面向对象模型(OOA)和面向对象设计模型(OOD)。对塔设备CAD中所遇到的技术问题进行了研究，建立了可靠的材料性能数据库、标准零部件数据库和设备材料数据库，采用从局部到整体的优化方法进行了塔设备的强度计算，并在此基础上以Windows2000为平台，Visual C++6.0为开发工具实现了代码重用性好、可读性好、易维护、易修改、易扩充的零部件设计系统。 本文提出了塔设备总装配图的解决方案，采用参数化方法，ObjectARX为开发工具建立了化工设备的零部件图形库和总装配图，设计并实现了装配图的消隐算法。系统还设计了塔盘设计模块，实现了塔盘设计的自动化。TCAD系统集结构设计、计算校核、文档编制和装配图自动生成等功能于一身，可以大大减少设计人员的工作量，提高塔设备设计效率。更多还原

【Abstract】 The Tower CAD (TCAD) is the combination of traditional industry and information technology. Techniques on CAD(Computer Aided Design) have been widely applied in many fields of our society after many years’widespreading. The result proves that the application of CAD can increase productivity obviously.But application of CAD on pressure vessels isn’t widespread because of its particularity. Towers are widely used in chemical industry, petrolic industry and other industries, and are of great influences on investment and manufacturing efficiency. It is necessary to develop a CAD software on tower.This paper discusses the function requirement, system analysis, system design and system realization on tower CAD, studies how to analize the software with the Object-Oriented technology. It also proposes the prototype,builds Object-Oriented Analysis model (OOA)and Object-Oriented Design model (OOD) using OMT(Object Model Technology). At the same time, it studies problems in tower CAD, sets up many open independent shared databases on material capability, standard parts and materials. It calculates tower stresses with an optimal method of from part to whole, on this basis it develops the parts system have the advantage of code high reusing, easily being understood,maintained,changed and expanded with Visual C++6.0 on the platform of Windows2000.This paper advances a valid solution to generate the assembly drawing, designs an algorithm to clean covered lines using parametering method with ObjectARX. The TCAD also designs the module of tray design, it -realizes that designs the tray automaticly. TCAD integrates functions such as structure design, stress checking, document compiling and assembly drawing generating, and can greatly simplify the work of designer and improve their efficiency.更多还原
