ABSTRACT = {To investigate the deposition distribution of snow particles in the bogie 
surfaces of a high-speed train, a snow particle deposition model, based on the critical 
capture velocity and the critical shear velocity, was elaborated. Simulations based on the 
unsteady Reynolds-Averaged Navier-Stokes (RANS) approach coupled with Discrete 
Phase Model (DPM) were used to analyze the motion of snow particles. The results show 
that the cross beam of the bogie frame, the anti-snake damper, the intermediate brake 
clamps in the rear wheels, the traction rod and the anti-rolling torsion bar are prone to
accumulate snow. The accumulation mass relating to the vertical surface in the rear 
region, horizontal surface in the front region and the corner area of the bogie is high. The 
average snow accumulation mass for each component ordered from high to low is as 
follow: traction rod, frame, bolster, brake clamp 2, anti-rolling torsion bar, brake clamp 1, 
transverse damper, axle box 2, axle box 1, air spring, anti-snake damper, tread cleaning 
device. The snow accumulation mass on the front components of the bogie is more 
significant than that relating to the rear components. Particularly, the average snow 
accumulation mass of rear brake clamp 2 and axle box 2 is about twice as high as that of 
the front brake clamp 1 and axle box 1.},
