Abstract: In order to cultivate students' or R &D personnel's ability to take safety protection into consideration in product design and improve the essential safety level of products,a system for training in mechanical safety protection was developed.At the same time,a virtual reality training system for mechanical safety and protection,consisting of 4 modules,such as risk assessment learning,safety distance learning,safety device learning and safety protection assessment,was developed with the prototype of the physical training system for mechanical safety and protection,and a manual of mechanical safety protection training system with virtual and real combination was put forward.The results show that the mechanical safety protection system with virtual and real combination has made great use of the complementary advantages of a physical system and a virtual reality system,that it can improve the teaching quality and learning efficiency of mechanical safety knowledge,reduce the cost and risk of the experiment,and be helpful for users to solve the related problems by combining theory with practice.

Key words: mechanical safety, virtual reality, training system, virtuality and reality combination, safety controller
