Pressure Characteristics on Korean High-Speed Railway Acoustic Screen Using 1/61-scaled Moving Model Rig

초록

The experiments for aerodynamic characteristics on railway acoustic screen are performed using 1/61 scale-down mock-up facility. The train model for the experiment is high speed train (KTX) and the tested speed is about 300km/h. The tested train length is about 61cm which is corresponding to two units of KTX train. The strength of pressure wave is measured using piezo typed pressure sensor. The measured pressure is compared with field test data and UIC 779-1[2] values.
