Challenge and Visualization in Railway Simulation by Particle Method

Abstract

Particle method is not suitable for simple fluid analyses because of precision. On the other hand, the particle method can efficiently solve such problems which occur large deformation of the boundary surface and a lot of collision detections. In this article, a wheel rolling contact analysis for water droplet on a rail as the former analysis and a snow accretion analysis for a train bogie by flying snow in train running as latter are introduced. In this article, photorealistic visualization by the POV-Ray and a reduced model with calculation results by the 3D printer are introduced.
