【摘要】：机械基础实验教学是高等院校工程类专业实验教学重要的组成部分。完整的课程体系不仅是学生获得知识的重要途径，同时对全面培养学生的科学作风、实验技能以及综合分析、发现和解决问题的能力，使学生具有创新、创业精神和实践能力起到重要的作用。虚拟现实（Virtual Reality，简称VR）技术是建设虚拟实验室的重要支撑技术之一。近年来，VR技术在机械设计、装配，样机制造各领域都得到了广泛的应用。国内外也已有部分高校初步建立了虚拟实验室，但由于机械基础类实验对过程的运动仿真要求非常高，目前系统化的机械基础虚拟实验室很少。本文构建了机械基础虚拟实验系统框架，对虚拟实验中的若干关键技术问题进行了深入研究，选取典型实验实现了基于虚拟现实技术的机械基础实验教学平台，较好地弥补了传统实验教学中存在的不足。本文的主要工作如下：（1）深入分析了机械基础实验教学的结构体系，针对实际教学需求，构建了机械基础虚拟实验室的系统框架。（2）对机械基础虚拟实验室的模型进行了分类，从人手的生理结构出发，对虚拟手的静态建模、动态控制和人机交互进行了分析和研究，提出了具体的解决方案，建立了数据手套与虚拟手的映射关系，实现了人机交互。（3）对机械基础虚拟实验中的碰撞检测、约束导引等虚拟实验中的核心技术问题进行了深入研究，，并提出了相应的解决方案，对虚拟实验室软硬件系统的集成技术进行了深入研究，实现了数据手套及位置跟踪器与虚拟实验室的集成。（4）基于以上工作，以EON Studio作为虚拟现实平台、3DMAX作为建模工具，结合EON SDK、5DT SDK和FASTRAK SDK，对机械基础虚拟实验室进行了开发，构建了逼真的实验场景，实现了机械基础虚拟实验室各功能模块。基于双通道立体投影系统对虚拟实验室进行了实验效果验证，并对虚拟实验室的网络发布进行了有益尝试。
[Abstract]:Experimental teaching of mechanical foundation is an important part of experimental teaching of engineering major in colleges and universities. A complete course system is not only an important way for students to acquire knowledge, but also an important way to cultivate students' scientific style of work in an all-round way. Experimental skills and the ability to find and solve problems through comprehensive analysis make students have the ability of innovation, entrepreneurship and practice. Virtual reality plays an important role in virtual reality. VR-based technology is one of the important supporting technologies in the construction of virtual laboratory. In recent years, VR technology has been used in mechanical design and assembly. Prototype manufacturing has been widely used in all fields. Some colleges and universities have initially established virtual laboratories at home and abroad, but because of the mechanical foundation experiments, the process motion simulation requirements are very high. At present, there are few systematic virtual laboratories of mechanical foundation. In this paper, a mechanical basic virtual experiment system framework is constructed, and some key technical problems in virtual experiment are deeply studied. Typical experiments are selected to realize the experimental teaching platform of mechanical foundation based on virtual reality technology, which makes up for the shortcomings of traditional experimental teaching. The main work of this paper is as follows: 1) the structure system of mechanical basic experiment teaching is deeply analyzed, and the system frame of mechanical basic virtual laboratory is constructed according to the actual teaching demand. This paper classifies the models of the mechanical basic virtual laboratory, analyzes and studies the static modeling, dynamic control and man-machine interaction of the virtual hand from the physiological structure of the human hand. The concrete solution is put forward, the mapping relationship between data glove and virtual hand is established, and the man-machine interaction is realized. 3) the key technical problems in virtual experiments such as collision detection, constraint guidance and so on are deeply studied, and the corresponding solutions are put forward. The integration technology of hardware and software system of virtual laboratory is deeply studied, and the integration of data glove and position tracker with virtual laboratory is realized. Based on the above work, using EON Studio as virtual reality platform and EON SDK as modeling tool. 5DT SDK and FASTRAK SDK, the virtual laboratory of mechanical foundation has been developed, and a realistic experimental scene has been constructed. The functional modules of the mechanical basic virtual laboratory are realized, and the experimental results of the virtual laboratory are verified based on the dual-channel stereoscopic projection system, and a useful attempt is made to publish the virtual laboratory on the network.
