【摘要】 在实施素质教育的今天，创新人才的培养，迫切要求我们在教学中加强实验教学，虚拟现实技术和多媒体技术为实验教学的发展带来了新的契机。为了提高教学效率，优化教学过程，加强实验技能培养。本课题将虚拟现实技术与多媒体技术有机的结合起来，在现有的硬件和软件基础上开发了材料加工虚拟实验室软件系统，为学生提供了一个人机交互、界面友好、开放式的学习环境。 首先利用VB语言构建了材料加工虚拟实验室软件系统平台，建立了材料成型与控制、模具设计与制造和焊接三个虚拟实验室。学生可以选择不同的实验，对实验进行浏览，选择实验过程参数，并能完成原砂性能、模具拆装，凝固过程数值模拟等简单实验。 在Windows2000环境下，利用Office2000中的Microsoft Access软件建立包含材料加工虚拟实验室的数据文件及图形和视频文件的虚拟数据库系统(VDBS)，并建立了相应表间的关系。利用Windows建立了OLE DB数据库连接。通过调用Visual Basic 6.0中的ADO控件进行数据连接，主要完成实验中用到的实验设备、仪器、工具和实验结果等数据的存储。建立相应的位图、文字和多媒体动画的数据库。 利用UG和SolidWorks等CAD软件和HZCAE系统完成实验数据的设计。其中包括成型理论实验和模具拆装实验中应用的三维实体模型，成型理论实验涉及到的温度场、流动场、和模拟充填的图片。 在上述研究的基础上，应用先进的ASP技术，进一步开发了材料加工虚拟实验室的Web访问系统。实现了学生的在线登陆，浏览和进行实验，提交报告以及与指导教师在线交流的功能。 本系统的开发成功有力的配合了学校提出的实现数字化校园的建设方针，实现了从环境(包括设备、教室)、资源(图书、讲义、课本、信息、软件等)到活动的全部数字化。更多还原

【Abstract】 Due to quality education policy and requirement of creative talents, it is imperative for universities to strengthen experimental teaching. And virtual reality technique brought new chance for it. With this technique experimental skill teaching efficient and process were improved. Combining techniques of virtual reality with multimedia, this paper researched virtual laboratory software system of materials processing engineering on basis of existing software and hardware. And this system provided a opening surrounding of person-computer alternation, friendly interface.Firstly, Virtual laboratory software system of material processing was established based on Visual Basic algorithms in this paper, which consists of material forming and control, mould design and manufacture, and welding virtual labs. So that the students can choose different labs and parameters in order to do some simple experiments as character of nature sand, mould assemble and numerical simulation of solidifying process.On Windows2000 software, this article established a virtual database system including data files, figures and video files of material processing virtual lab and built the relation of tables. At the same time, with software of Windows OLE DB database connection was set up. Using ADO of Visual Basic 6.0 to connect the data, the database mainly saved experimental equipments, apparatus, tools and results and established databases of digital figures, words and multimedia flashes.Based on CAD software such as UG and Solidworks and HZCAE system, experimental data design was researched, which includes three-dimension solid model and some figures of temperature field, flowing field and simulation filling in shape theory and mould dismount-installation experiments.Ground on the previous research, with technique of ASP this paper invented web part of the system that made students land the web, explore and experimentize, put in experimental report and communicate with the teacher on line.The research coordinates with the policy of building digital campus made out by the university to digitize from environment, resource to action.更多还原
