Raw data of particles accumulation in wind tunnel lab on the bogie of high-speed train in different cases

When high-speed train runs in environment with a large number of airborne particles which may accumulate on the bogie of the train, the normal operation of the bogie will be affected to reduce the riding comfort and train safety. The protective devices around the bogie were normally considered as an efficiency opinion to reduce the entry of particles into the bogie area. However, at present, there are relatively few analyses on the protective effects of diverse protective measures against different types of particles. In order to test the protective effects of shirt boards and spoilers, the airborne particle transport processes around the bogie were simulated in wind tunnel Lab. Three kinds of typical particles, including artificial snow particle, wheat bran, sieved soil, were employed to represent the different statuses of airborne particles in real conditions. Three parameters, including the relative reduction ratio (for artificial snow particles), the relative particle flux reduction ratio of fine wheat bran, and the relative concentration reduction ratio of fine sieve soil particles, were taken as the indexes to assess the protective effects.
