Motion simulation of a railway vehicle bogie along direct waved railway

J. Siegl, J. Švígler
pages 1143 - 1158, full text

This paper is devoted to the dynamical analysis of a vehicle bogie motion along a direct waved railway. A mathematical model of the discrete multibody system that consists of one half vehicle case and a bogie with double suspension is created. The exact time change of a wheel-rail contact point position during vehicle motion, when a wheel carries out a general spatial motion, is included into the solution. The rails and vehicle wheels are interconnected through the creep force effects. Numerical solution and graphical visualization of the vehicle bogie motion with the constant vehicle forward velocity, with consideration of variable creep force effects, is performed. The results are compared with vehicle bogie motion along the direct not waved railway and an influence of railway waviness to the vehicle bogie motion stability is shown.
