As computer science and information technology develop rapidly, virtual reality (VR) technology increasingly affects every aspect of daily life especially in the field of education. Applying virtual reality technology (Virtual Reality - VR) in mechanical vocational training brings many benefits and significant reforms in the learning and practice process of students and workers. VR allows creating accurate simulations of working environments in specialized mechanical engineering, helping learners become familiar with equipment, machines and work processes without having to directly interact with pre-existing equipment. or dangerous. Practice exercises in VR can help learners develop practical skills safely and effectively. Furthermore, VR provides the ability to interact directly and receive immediate feedback, helping students better understand processes and techniques, thereby improving their skills. Using VR in training helps reduce costs associated with using and maintaining realistic mechanical equipment, and VR simulations can be used repeatedly without wear or damage. Besides, VR creates an engaging and interesting learning environment, enhancing students’ learning motivation as well as other communication methods. This technology also allows the organization of distance learning courses, helping students in different locations participate in training programs without having to move. The research focuses on understanding the application of VR technology research in mechanical engineering training. The research results solve limitations in mechanical engineering training. This contributes to improving the quality of teaching and practice, providing a solid grasp of basic and advanced technical operations in vocational training.
