Traditional experimental teaching has the problems of limited teaching resources, ABSTRACT. and difficult to understand teaching content, and high risk of teaching experiments. This article aims to provide virtual and realistic experimental scenes through the design of the experimental teaching system of virtual reality technology. The experimental teaching system designed in this paper includes graphic teaching, virtual scene construction, simulation experiment, teaching skill evaluation four functional modules. Use Photoshop, 3Ds Max, Maya, Unity 3D, etc. to complete the system development. In order to verify the actual use of the system, we conducted a survey on some students of mechanical design majors in colleges and universities, and concluded that the students were quite satisfied with the system's interface evaluation, functional design, interactive operation, and software operation. 72% of students believe that the system is stable and stable after the long-term operation, and the operation is relatively normal, with good performance and compatibility; 80% of the students think they can clearly understand every step of the experiment. The research of this paper has great application value for professional teaching with strong practicality.
