Virtual experiment teaching is an important part of higher education institutions and research institutions. It plays an important role in helping students develop basic experimental research capabilities and innovative experimental research concepts. Mechanical majors focus on the cultivation of students' practical hands-on ability, but the traditional mechanical experimental equipment update iteration is slower, the experimental cost is higher, and there are potential safety hazards. In order to solve the problems encountered in the above mechanical experiment teaching, this paper focuses on the characteristics of the mechanical disciplines, after analyzing the development of virtual experiments at home and abroad, using the B/S architecture, Bootstrap framework and Hibernate technology, and the virtual reality technology and augmented reality technology in Unity3D environment are used to design and implement the mechanical virtual experiment teaching platform. Users can select the corresponding experiment in the virtual platform. In the experiment, the parts can be viewed from different perspectives. After the experiment is completed, the experimental result information can be obtained, and the experiment report can be completed online, which effectively saves teachers and students time. Through the survey of 518 students and 52 teachers who used this platform, most of the teachers and students agreed with the rich multimedia resources, friendly interaction and convenient collaborative communication of the mechanical virtual experiment teaching platform.

虚拟实验教学是高等教育机构和研究机构的重要组成部分。它在帮助学生发展基本的实验研究能力和创新的实验研究概念方面发挥着重要作用。机械专业侧重于学生动手能力的培养，但传统的机械实验设备更新迭代较慢，实验成本较高，并且存在潜在的安全隐患。为了解决上述机械实验教学中遇到的问题，本文重点研究了机械学科的特点，在分析了国内外虚拟实验的发展情况之后，采用了B / S架构，Bootstrap框架和Hibernate技术，利用Unity3D环境下的虚拟现实技术和增强现实技术，设计并实现了机械虚拟实验教学平台。用户可以在虚拟平台中选择相应的实验。在实验中，可以从不同的角度查看零件。实验完成后，可以获得实验结果信息，可以在线完成实验报告，有效节省了师生的时间。通过对使用该平台的518名学生和52名教师的调查，大多数师生都同意机械虚拟实验教学平台的丰富的多媒体资源，友好的交互和便捷的协作通信。
