基于solidworks球阀参数化设计
摘要
制造科学与工程学科是一门古老的传统学科，随着计算机技术的不断渗透和融合于工程设计、制造、检测、管理等方面，制造学科正在发生革命性的变化，涌现出许多以计算机为基础的新理论、新技术和新方法，形成了一系列计算机应用技术和自动化信息系统。信息技术就是一门处理资料、信息的新兴学科。CAD也就是信息技术在工程与制造业中的应用。
三维CAD技术作为数字化设计的主体成为工业领域普遍应用的关键技术，是现代产品开发的核心手段和主导环节，对提高企业的产品开发能力，增强产品的市场竞争力具有巨大的作用。特征造型是CAD建模方法的一个重要的里程碑。特征的引用直接体现了设计意图，使得产品模型更易于为人理解和组织生产，为开发新一代的基于统一产品信息模型的CAD集成系统创造了条件。国内开发的阀门CAD系统大部分都是二维的，已经无法满足用户的方便、易学、直观的需求，因此迫切需要开发出一个功能完善且价格适中的阀门CAD系统以满足工程人员的需求。
基于上述存在的问题，本文开发了基于solidworks球阀参数化设计。按照软件工程的方法，采用面向对象的开发技术和关系型数据库，开发的一套商品化、大型的阀门设计CAD系统。本文以数据库为支撑，并基于soliworks实现零部件的参数化设计、零件模型及装配模型的建立和主要零件工作图的绘制；实现球阀设计、绘图和标准化、可视化、自动化。
本文对三维参数化技术及利用面向对象编程语言VB对soldworks的二次开发技术在阀门CAD系统上的应用做了探讨与研究。建立了以模板零件为数据驱动源的二次开发方式，实现了阀门零部件设计结果及任意修改的尺寸参数均可驱动模板零件作相应的更新，生成用户所需的零件。实践证明。本文采用的此方法是一种较为理想的参数驱动方法。其开放性强。运行速度快，便于管理与维护、尤其适用于系列化、品种多样化的阀门行业。

Based on Parametric Design Solidworks Ball
Abstract
Manufacturing Science and Engineering is one of the oldest traditional disciplines , with the penetration and integration of computer technology in engineering design, manufacturing, testing , and management , manufacturing discipline is undergoing revolutionary change , the emergence of many computer-based the new theories, new techniques and new methods , forming a series of computer application technology and automated information systems. IT is a process the data , the emerging discipline of information. CAD is the application of information technology in the engineering and manufacturing of .
3D CAD technology as the digital design industry body become a key technology in general use , are the core of modern product development tools and leading sectors , to improve enterprise product development capabilities , and enhance market competitiveness of products has a huge role. Feature-based modeling is an important milestone CAD modeling methods . Referenced directly reflects the characteristics of the design intent , making the product easier for people to understand and model the organization of production , for the development of a new generation of integrated CAD system based on a unified information model to create the conditions . Most of the domestic development of the valves are two-dimensional CAD system , has been unable to meet the user's convenience , easy to learn , intuitive needs, there is an urgent need to develop a fully functional and affordable CAD system to meet the needs of valve engineering staff .
Based on the above problems , this paper developed based on parametric design solidworks ball . The method according to software engineering , object- oriented development and relational database technology , the development of a commercialization of a large valve design CAD system . In this paper, database support, and soliworks achieve parametric design components based on building parts models and assembly models and key parts work diagram drawing ; realization ball design, drawing and standardization , visualization and automation.
In this paper, three-dimensional parametric techniques and the use of object-oriented programming languages VB on soldworks secondary development technology in the CAD system to do a valve to explore and research. Established a template for data-driven part of the secondary source development methods to achieve the results and any valve component design parameters can modify the size of the corresponding part of the drive to update the template to generate the user the necessary parts . Practice has proved that . This method is used in this paper is an ideal parameter-driven approach . Its openness and strong . Fast, easy to manage and maintain , especially for the series, species diversity in the valve industry .
