Research On Virtual Reality Simulation Of Metro Vehicle And Environment

With the development of the city traffic congestion, city rail transit vehicles become the essential means to solve the traffic congestion. Predictably, the coming decades will usher in a rail vehicle development boom. Based on the above background, this paper discusses the feasibility and rationality of the development of the virtual reality simulation system of rail transit vehicles by using virtual reality technology. Finally, the design and development of the virtual simulation system of rail transit vehicle is completed.This paper first analyzes the background requirements and the overall analysis of the system and the various modules of the system are analyzed in detail. And the design goal and the design scheme of each module are confirmed by the requirement and analysis. The design of the model, the construction scheme of the virtual scene, the design of the user interface(UI), the interaction of the software and hardware and the design scheme of the communication are confirmed. Then, the establishment process of the virtual reality simulation system and the steps and key points of each module are described in detail. Including: the establishment of three-dimensional model, the construction of the virtual scene, the establishment of the user interface, the realization of the interaction between software and hardware, the communication between the program and the communication between different systems. At last, the paper discusses the system implementation process of key technologies and technical difficulties, train operation control, train running path generation, train driving realization of logical and display various picture effects and other technical difficulties have been solved through the research of. At the end of the paper, it summarizes the problems in the process of the system completion and the deficiencies of the current system, and prospects and plans for the future improvement and optimization of the system.The virtual reality simulation system can simulate the running environment of the subway in real time. And it can be docked with the semi physical simulation system of rail transit. The online version can test the performance of Metro Trains. It can make the test result more intuitive, and avoid the shortcomings of the real test, and make the test safe, economical and reliable. Single version can be used for the driver's training, and as an experimental equipment used in Colleges and Universities. The single version is also able to simulate the planning and operation of the subway lines. And it is possible to optimize the subway line in the subway planning stage.
