Research On Key Techniques Of Railcar Simulation Training System Based On Virtual For Reality

With the rapid development of the railway industry,a variety of new trains are used for practical transportation,which makes the train driver's driving skills have a new demand.The training methods of the traditional real train drivers have been gradually replaced by more scientific,advanced and efficient simulated driving training systems due to training costs,training cycles and safety reasons.Simulated driving equipment has been widely used for its powerful functions Which is used in the fields of railway,aerospace,navigation and so on.The virtual driving system based on virtual reality creates a virtual driving environment through virtual reality technology,which realizes the real operation process in the training process and interacts with the virtual environment.The driver of the driver training and assessment.Based on the virtual reality of the rail car simulation driving system is the driver of the rail car driver training and assessment specifically for R & D design,mainly for the railway bureau and railway institutions.This paper designs and realizes the simulation driving system of the rail car,and applies the virtual reality technology to the simulated driving system,and studies the key technical difficulties in the simulation system of the rail car during the design and realization process.Based on the application of the simulated driving system at home and abroad and the dynamic analysis of the research,the paper puts forward the overall design scheme,hardware design scheme,software design scheme and system business process of the simulation system of the rail car simulation system,and from the software And hardware aspects of a detailed description of the simulation driving system in the realization of a functional module.After the establishment of the program,the key technical difficulties of establishing the mathematical model of the simulation system of the rail car are analyzed,and the detailed research and the solution are put forward.At the same time,the visual simulation system and its key technology in the simulation system of rail car are studied in detail.In this paper,the design of the orbital vehicle simulation driving system simulation simulation of the rail vehicle operation control algorithm,track vehicle operation and DMI human-computer interaction interface.The vehicle simulation driving system is mainly composed of driver operation module,computer control module,rail car running control module,teacher module and visual module.In the process of designing the simulation vehicle driving system,the mathematical simulation model of the simulated driving system is established.It is the key part of the simulation system of the whole vehicle,and the simulation software of the simulated driving system is established by constructing the mathematical model.Simulated driving system simulation scene using virtual reality technology to create visual animation,making the scene more realistic,the driver's console is in full accordance with the actual rail car to design the bridge,set up in the teacher machine training functions,assessment functions and Evaluation of the scoring function,simulated driving system monitoring equipment in the training process of monitoring functions and control logic are in accordance with the actual rail car running control equipment to carry out research and development.
