摘要
随着高等教育信息化的迅速发展,虚拟网络教学作为一种新的教学模式,正迅速的
发展并得到越来越广泛的应用。其具有丰富的多媒体资源、便捷的协同交流、友好的互
动等独特的优势。
实验教学作为机械学科教学的重要部分由于各大高校实验室设备参差不齐,实验成
本相对较高等劣势,在各大高校中还不能一致达到较好的教学效果。基于网络的虚拟实
验教学平台有效地解决了这一问题,通过该平台,可以开发出复杂而又实用的先进设备,
让学生形象深刻的了解设备中机构的运动原理,掌握知识本身;另一方面,该平台很好
的解决了学生学习时在时间和空间上的局限性。
本文在分析虚拟实验国内外发展状况,通过对各种学习理论的对比和各种虚拟现实
技术研究比较后,针对机械学科的特点,基于人本主义学习理论和新媒体理论,提出了
两套解决方案,分别为基于 EON 的 VC++技术和基于 Flash 的 Flex 技术,开发出一套针
对机械学科的基于网络的虚拟实验教学平台,将对设备的自主观察、自主拆装,自主规
划连接,三维仿真,自动对相应运动进行计算分析的技术集成于一体,具有可视化,交
互性强,可扩展可开发等多种优势。
目前该虚拟实验平台已经运用到实际教学过程中,通过教师和学生使用反馈,经过
不断完善和改进,虚拟实验平台最终将得到了实际运用。

Abstract
With the development of higher education informatization ,Online education as a new teaching model
has been quickly developed and widely used. It has many advantages , such as rich multimedia resources,
convenient munication , friendly interaction and so on.
Experimental teaching , as an important part of the teaching in mechanical field has not got a good
performance as a result of aboratory equipments of many universities are uneven and experimental cost
relatively high , we design a virtual experiment platform which solve the problem effectively. On this
platform ,we developed advanced equipments which plex and practical so that students can
understand the kinematic principle of the mechanical equipments well. On the other hand , This platform
can solve the problem that students have time and space limitations when they are studying .
Based on analyzing the home and aboard status of virtual experiment research and omparing the
development of several virtual reality technology, in mechanical field, using the media theory and the
humanism theory as director, I has proposed two new sets of building virtual experiment system , they are
communication between VC++ and EON , communication between Flex and flash. By using th
