Abstract
In order to study the influences on catenary’s safety by high-speed train passing through the tunnel, the numerical simulation method and the sliding mesh technology are used to simulate respectively the processes of different high-speed train combinations passing through single track tunnel and double track tunnel at the speed of 350 km/h. The characteristics of piston wind in the tunnel by are obtained monitoring the air velocity and air pressure at the davit. Based on aerodynamic performance simulation results, the wind-induced vibration response of the contact line is simulated to obtain the range of the aerodynamic noise and the contact line displacement. The results show that the speed of the train winds is increasing with the increase of the train length and train speed and the decrease of the tunnel section, the higher the train speed, the more remarkable the aerodynamic performance. The contact line has the maximum forward displacement of 2. 92 mm the moment when the train enters the tunnel.关键词
