Design and Practice of Virtual Simulation Experimental Teaching in Colleges and Universities Based on Unity3D

In order to improve the efficiency of experimental teaching in colleges and universities and the comprehensive ability of students, this paper constructs a virtual simulation experimental teaching system based on Unity3D. It adopts modular architecture design, integrates scene construction, interaction logic, intelligent feedback and evaluation and other key technologies to complete the optimization of teaching content and process implementation. The effectiveness of the system in improving teaching quality and reducing resource consumption is verified through the case of “Mechanics of Materials Experiment”. The study shows that the system not only improves the efficiency of the experiment, but also significantly enhances the practical ability and innovative consciousness of students, which provides theoretical and practical support for the wide application of virtual simulation experiment in education.
