Research On Mechanical Safety Protection System Based On Virtual Reality

Mechanical safety is the guarantee of the survival and development of the manufacturing industry,which is related to all aspects of the national economy and people's health and safety.With the development of virtual reality technology,virtual simulation experiments are applied to teaching and research more and more.Carrying out research on mechanical safety protection system based on virtual reality can provide a new idea for the education of mechanical safety.Firstly,according to the current mechanical safety teaching and research requirements,a set of general design scheme for virtual reality system of mechanical safety protection is put forward.Creo,3ds Max,and Unity3D are selected as the system development platform.The system development process based on HTC Vive is determined.Secondly,the key technologies for the realization of virtual reality system are studied.Combining the functional features of the Unity3D engine,the geometric transformation of the object is realized by the member variables and functions of the Transform component,the collision detection of objects is realized by using the bounding box technology based on the PhysX physical engine and the collision detection response function,the 3D immersive display of virtual scene is realized with the help of HTC Vive head device and SteamVR plugin,the network communication of the system is realized by using Unity3D built-in network function and remote procedure call RPC technology.Thirdly,a multi software collaborative 3D modeling method based on Creo,3ds Max and Unity3D is proposed.The realistic mechanical devices,training classrooms,virtual personas and particle models are established.At the same time,the optimization method of the model is studied,and the scene model of the system is constructed.Finally,according to the characteristics of mechanical safety technology,the risk assessment,safety distance,safety device and safety protection test are designed.Unity3D engine and C#language script are used to realize the functions of risk analysis and evaluation,the safety distance experience learning of different dangerous touch methods,the work process simulation of different safety devices and the evaluation of safety protection.
