The Research of the Numerical Simulation on the Granular Ballast Bed Tamping Xuejun Wang1, a, Yilin Chi1, b, Wei Li2, c, Taoyong Zhou1, d, Xingli Geng1, e 1Faculty of Mechanical & Electrical Engineering,Kunming University of Science & Technology,253 Xue Fu Road, Kunming, 650093, P.R.
Because a railway track bed belongs to the discontinuous structure, and the traditional finite element method is based on the materials continuity hypothesis, so it is difficult to solve the kinematics problem of ballast particles.
