摘要
虚拟实验有助于提高学生的学习兴趣和动手能力。针对机械基础实验教学的特点,对基于VRML的虚拟实验系统进行功能分析和结构设计,并对虚拟模型的建立和优化、虚拟实验中的交互以及交互过程中对数据库的访问等关键技术进行研究,最后以冲击实验为例进行系统的构建。研究表明,基于VRML的机械基础虚拟实验系统是切实有效的。
Virtual experiment can improve student interest in learning and practical ability. Aimed at the characteristics of experimental teaching, the functional analysis and the structural design of virtual experimental system based on VRML were carried on. Besides, many key technologies were studied, such as the establishment and optimization of virtual model, the interaction of virtual experiment, the database visit in interactive process. Finally, the system was eonstruc- ted with an example of impact experiment. The results show that it is valid and effective.
