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 directl y use applications on remote server , communicate with other designers on intranet / internet , share software resources and realize long - distance cooperative design 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。
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 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。
