[0002] Virtual reality technology is a computer system that can create and experience virtual worlds. It has three outstanding features, namely, interactivity, immersion and conception. Virtual reality technology is also an important direction of simulation technology. It is a combination of simulation technology and computer graphics. A collection of technologies such as man-machine interface, multimedia technology, sensor technology and network technology. Virtual reality technology mainly includes simulated environment, perception, natural skills and sensor equipment. The simulated environment is generated by computer graphics technology. Visual perception, in addition to hearing, touch, force, movement and other perceptions, even smell and taste, also known as multi-sensory, natural skills refer to human head rotation, eyes, gestures, or other human behaviors , the computer processes the data adapted to the participants' actions, and responds to the user's input in real time, and feeds back to the user's actual experience respectively. The sensing device refers to the three-dimensional interactive device, and the tamping series vehicles belong to large-scale road maintenance machinery. Equipment, used for the maintenance and repair of railway trunk lines, the tamping car is a large-scale mechanical equipment integrating machine, electricity, hydraulic and gas. Its control structure is complicated, the equipment is expensive, and the precision of line maintenance is high. The requirements are high. At present, the training of operators adopts the method of following the train with the real train. The cost of following the train is high, and the time for practical training is insufficient. There are certain risks and hidden dangers to the railway operation, and it is impossible to actually experience the problems encountered during the tamping process. In special cases, simulation / simulation technology can be used to completely simulate the operation process of the tamping vehicle, which can not only solve the problem of real vehicle training, but also conduct technical research on the tamping process to improve the accuracy of tamping operations
