Abstract:
The device for testing the flow field state in bogie cabin of high-speed train was designed. The flow field in bogie cabin was analyzed by numerical simulation method, under the conditions of no crosswind, crosswind speed of 15 m·s-1 and end plate angles of 30°, 45° and 70°. The effect of skirt plate covering on accumulated snow formation was analyzed. Test result shows that the test and simulation results of airflow motion laws are coincident, so the simulation is feasible. Airflow enters into bogie cabin from train bottom and skirt plates of two sides. The flow separation phenomenon happens when airflow flows past end plate. Most airflow comes out from end plate bottom and skirt plate backs of two sides. The speed of airflow past bogie cabin decreases gradually from head car to back car, air inlet area at skirt plate decreases, and air outlet area at skirt plate back increases. Snow grains are taken into bogie cabin by airflow past the cabin bottom and deposit continuously under the effect of flow field of bogie to form accumulated snow. Reasonably setting end plate angle of bogie can decrease the accumulating probability of snow in bogie cabin. Covering skirt plate can not decrease accumulated snow in bogie cabin, and is not recommended. 1 tab, 21 figs, 18 refs.
