Abstract:
In order to analyze the characteristics of initial compression wave generated when a high-speed maglev train enters a tunnel, the three-dimensional compressible unsteady flow N-S equation and the SST κ-ω turbulent flow model were used. Based on the overlapping grid method and the finite volume method, taking the head shape of a high-speed maglev train with a speed of 600 km·h-1, which was developing in China as a research object, a calculation model of a high-speed maglev train entering a tunnel was established. By analyzing the pressure and pressure change rate at different measuring points on different cross sections from entrance of tunnel, the spatial distribution characteristics and propagation characteristics of initial compression wave when the train heads enter into the tunnel opening were obtained, and the effect of different speeds on the amplitude of initial compression wave fluctuation were also obtained.Research result shows that the initial compression wave starts to form before the train enters the tunnel. It has three-dimensional characteristics at the initial stage of formation. At the same height of the tunnel cross section, the pressure of initial compression wave on the side closer to the train body is greater than the pressure on the side farther from the train body. On the same side of the tunnel cross section, the lower the height near the train body, the higher the pressure of initial compression wave, but the pressure of initial compression wave on the side far from the train body is independent of the height. When the train enters the tunnel for a certain distance at the position about 36 m in front of the train head, the pressure at the same section in the tunnel is the same, and the initial compression wave changes from a three-dimensional wave to a one-dimensional plane wave. When the streamlined head of train enters the tunnel at about 0.15 m, the pressure change rate of initial compression wave at the 300 m measuring point at the tunnel reaches the maximum value. The higher the train speed, the greater the peak pressure of the initial compression wave. The peak pressure of initial compression wave at the 100 m measuring point at the tunnel is approximately proportional to the 2.5th power of the train speed, and the peak pressure change rate is approximately proportional to the 3rd power of the speed. 1 tab, 20 figs, 28 refs.
