【摘要】 CAD技术发展己经渗透到工业产品设计的每一个阶段,这使得传统的设计方法发生了巨大的变化。压力容器是化学工业、石油工业及其它一些行业中广泛使用的重要化工设备,其研究和开发倍受重视。压力容器设计和CAD技术的结合,将极大地提高设计质量和设计效率,缩短新产品开发周期。但是,由于CAD软件开发自身专业性强,现有的化工设备CAD软件还较落后于计算机应用技术发展的现状,在开发、维护、扩充和升级等方面还存在一系列问题。因此,研究和开发一套实用的化工设备CAD系统具有重要的价值。石化压力容器包括反应容器、分离容器等四个种类,是石化产业大型化的产物。石化压力容器的设计是一项比较复杂的机械产品设计工作。保证设计质量、缩短设计周期和提高设计效率,对其具有重要的意义。本文以石化压力容器为产品设计对象,应用最新的.NET平台开发技术、数据库技术和有限元技术,并运用先进的设计方法,为四川压缩机制造有限公司开发出了一套基于VB.NET的卧式压力容器CAD应用系统。该系统具有进行卧式压力容器主体设计、标准件库参数化绘图以及强度校核等功能,同时具有二维参数化设计绘图以及快速三维自动造型功能。本论文从当今CAD开发技术和开发工具出发,通过对.NET平台的研究,提出了基于.NET开发平台的可行性,并运用VB.NET开发了AutoCAD基本绘图功能模块,而且本系统采用了面向对象的程序设计技术以及DAO数据库开发技术。软件更多还原

【Abstract】 The development of CAD technology has affected every phase in the process of industrial product design, and this brought great changes to traditional design method. Broadly used in chemistry, petrochemistry and other industries as an important equipment, pressure vessel have received great attention on their research and development. The combination of CAD and pressure vessels’ design will increase the quality and efficiency of design and shorten the developing cycle of new Manufactures. But result from the considerable specialty of CAD software development, existing chemical equipment CAD software drop behind computer application technology and have a series of problems in development, maintenance, extension and upgrade. So it shows great values to figure out a practical set of chemical equipment CAD system.Petro-chemical pressure vessel, comprising four species including reactor and separator, is the outcome with the largening of scale in petro-chemical industry. The design of petro-chemical pressure vessel is a complicated design work of mechanical production. So it is of much important sense to guarantee its design quality, shorten its design period, and improve its design efficiency.With petro-chemical pressure vessel as the design object, this article has used the newest developing technology of .NET platform, database technology, FEA technology and advanced design methods, and developed a petro-chemical pressure vessel-CAD application system for Sichuan compressor manufacturing Ltd.. Main design of horizontal pressure vessel, parametric design & drawing of standard parts and intensity check can be realized in this system. This system mainly has also two更多还原
