摘　　要：为解决农业机械实验教学环节存在的学生自主实验能力不强、综合性创新性实验难以开展等问题,以旋耕机、翻转犁、深松机、播种机等典型旱地耕种机械为对象,依托虚拟现实、多媒体、人机交互、数据库和网络通信等技术手段,构建了包含"机具构造、工作原理、挂接调整、田间作业"4个环节3个层次的虚拟仿真实验教学系统,引导学生开展自主学习、深度思考与在线反馈,使学生在虚拟环境中开展交互实验,深入理解我国北方旱地机械化作业过程,从而达到"农业机械与装备"等相关课程教学大纲所要求的教学效果,提升实验教学质量。There are some problems in the experimental teaching of agricultural machinery,such as the weakness of independent experiment ability and the difficulty of carrying out comprehensive innovation experiment.In this paper,taking the typical dryland farming machinery such as rotary tillage machine,turnover plough,subsoiler and seeder as objects,a virtual simulation experiment teaching system which is consisted of machine structure,working principle,connection adjustment and field operation was constructed from four links and three levels on the basis of virtual reality,multimedia,human-computer interaction,database and network communication.Based on the system,the interactive experiments were conducted in virtual environment for the students to deeply understand the mechanization process of dryland in northern China,so as to achieve the teaching effect required by the course syllabus of agricultural machinery and equipment,and improve the quality of experimental teaching.
