摘要：
Inclined rubber guiding plate was designed for anti-snow problem of high-speed train bogie in blown snow conditions. Adopting the RNG k-ε turbulence model, air intake volume, flow line, flow velocity of the bogie area with different slant distances as well as its influence on car-body aerodynamic force were calculated and analyzed at the cross wind speed of 15 m/s and train speed of 200 km/h. The results show that bottom side is the major air intake source of bogie area. The total air intake volume of bogie area decreases as slant distance increases. Decrease rate of the total air intake volume can reach 50% when the slant distance grows from 40 mm to 60 mm. Air flow below the frontage bottom plate is changed by the installed guiding plate. Air streamline passes by the bogie cavity and goes straight to the rear bottom plate, which effectively decreases the air flow into the bogie area. As the slant distance increases, boundary layer separation of car-body surface occurs and aerodynamic drag increases by 2.4% compared with that of the original car. However, lateral force, lift force and overturning moment vary within 1.8 %, which has little effect on safety. © 2016, Central South University of Technology. All right reserved.
