【摘要】 根据阀门CAD发展趋势,针对成都乘风阀门有限责任公司阀门设计现状,本课题基于MDT三维设计平台开发了阀门三维参数化设计系统,主要完成的工作和成果如下: 根据公司提供的几种不同结构阀门的二维工程图纸,利用MDT三维设计平台建立了三维参数化基本图形库,其中包括所有零部件和总装配模型图及二维工程图;依照阀门设计的一般步骤设计了参数编辑器,用来对阀门尺寸参数进行编辑、输入、输出等,具有参数双向同步显示功能,使用十分灵活方便;根据用户的需求,为了使设计达到精确、可靠、实用的要求,设计开发了辅助计算器,能自动完成阀门设计过程中所需的各种结构计算,并可以输出阀门设计计算说明书;为了使设计人员更具有竞争力,本系统利用Internet/Intranet技术设计开发了虚拟设计中心子模块,虚拟设计中心集成了网络会议、终端服务、超级链接等功能,可以让设计师直接使用服务器上的应用程序,与Intranet/Internet上的其他设计专家进行交流、共享软件资源,实现远程协同设计。 应用已建立起的阀门三维参数化设计系统开发了“软密封胶板闸阀”、“撑开式平板闸阀”、“三偏心蝶阀”等四种结构的阀门基本图形库,可对这四种结构的阀门进行快速序列化设计,大大提高了阀门设计生产效率,并具有较强的可扩充性。
【Abstract】 Following the development trend of valve CAD,according to the requirements of the Chengdu ChengFeng Valve Limited Company and based on MDT,this article develops the 3D parametric valve design system. The main work and achievements are as follows:Based on the 2D engineering drawing of the several different valves the company provided,the 3D parametric basic drawing-base is set up using MDT which is a 3D design platform,including all the parts drawings and the general assemblage drawings of the valve models;In accordance with the common steps of the valve design,the parameter editors are designed to edit,import and export the valve parameters and are provided with the function of double synchronization on parameters displaying for convenience in use;In order to meet demands of users and make the design more accurate,reliable and practical,the assistant formula calculators are developed,which can automatically do all types of structure calculation in the procedure of valve design,and export the calculation manual of valve design;In order to make designers more rivalries,taking full advantage of InternetMntranet technology, the virtual design center is developed,which integrate netmeeting,terminal service and super links,so that the designer can directly use applications on remote server,communicate with other designers on Intranet/Internet,share software resources and realize long-distance cooperative design.Using the system developed,we have set up the basic drawing-base of four different valves such as resilient seated gate valve,the wedge flat gate valve and the three-eccentricity butterfly valve etc. So these four type valves can be rapidly designed. It is shown that this system realizes the valve quickly modeling,consumedly increases the valve design efficiency,and has stronger extensibility.
