Research on case virtual simulation teaching system for automobile engine based on Web 3D

At present, the traditional teaching methods rely on paper teaching and specific physical equipment, which is a lack of immersion. Moreover, it is experimentally costly and the teaching effect is not good. Therefore, this paper proposes a Web 3D virtual simulation teaching system for automobile engine based on case teaching method. The system mainly includes three modules: account management, 3D virtual simulation teaching based on typical cases and document reading. Unity3D software and database technology are used to build a realistic virtual experiment scene, so that students can simulate interactive experiments online and master learning skills to achieve teaching objectives. The experimental results show that the 3D virtual simulation teaching system proposed in this paper can realize online simulation of specific interactive experiments of disassembly and assembly for automobile engine. In addition, students can learn independently, so as to achieve the purpose of immersive learning, improve teaching efficiency and reduce costs. Most importantly, it can avoid teachers and students from being hurt in the actual experiment and provide a new way for teaching.
