【摘要】 计算机及网络的发展与应用使得制造业朝着“全球化”、“网络化”、“虚拟化”、“敏捷化”的方向发展。企业间需要通过信息共享、专业化协作来搭建世界级的制造和供应网络。基于Web的零件库系统由此应运而生,它充分利用网络技术,最大限度地共享企业内部和外部资源。本文研究的主要内容是基于Web的虚拟零部件库系统的设计与实现,包括系统总体方案设计、系统功能模块分析设计、系统软件测试及性能优化。在研究了零件库及虚拟现实技术在国内外的发展及应用现状,特别分析了零件库技术在铁路行业的应用现状后,采用了B/S模式的现代虚拟零部件库系统的设计思想进行设计。研究了Struts-Spring-Hibemate架构、计算机网络技术、网络数据库技术、三维CAD技术、虚拟现实技术及PDM等相关技术理论。对组成系统的各个子系统:产品管理子系统、留言管理子系统、信息中心子系统和系统管理子系统等进行了具体的功能分析设计与实现。系统经过测试和性能优化,基本达到最初的设计需求。与其他基于Web的零件库系统不同,本系统主要是针对铁路行业而设计开发的,所提供的模型也是铁路行业常用的轨枕模型及其配件,桥梁模型及其配件等,具有很好的实用性。更多还原

【Abstract】 Computer and network development and application makes manufacturing in the "globalization", "network", "virtual" and "agile" direction. Enterprises need information sharing, professional collaboration to build world-class manufacturing and supply network. Web-based parts library system makes full use of network technology to maximize shared internal and external resources.In this paper, the main contents are design and implementation of web-based virtual library system, including overall system design, analysis and design of functional modules, system software testing and performance optimization.In examining the development and application of the parts library and virtual reality technology at home and abroad particularly in railway industry, the system was implemented by making use of B/S mode. Struts-Spring-Hibernate framework, computer network technology, network database technology, 3D CAD technology, virtual reality technology, PDM and other related technologies are researched in the paper. Web-based parts library is composed of four subsystems: product management subsystem, message management subsystem, information center subsystem and system management subsystem. The design and implementation of them are carried out. The system reaches initial design requirements after testing and optimizing performance.This system is different from other web-based systems for it’s mainly designed for the railway industry, provides sleeper models and fittings, bridges models and fittings, has a good practicability.更多还原
