Dynamic Analysis of the Vehicle Running on Turnout at High Speed Considering Longitudinal Variation of Rail Profiles

Abstract

Recently, railroad systems are getting increased worldwide attention in order to reduce environmental pollution and traffic jam. The railway systems are light rail transit systems in city or high-speed railroad systems between cities. Up to now, dynamic behavior of the vehicle running on a turnout at high speed was NOT researched. In this research, dynamic behavior of the vehicle running on turnout at high speed was calculated using A’GEM (Multi-Body Dynamics program), which was developed to enable to calculate the longitudinal variation of cross-section of rail profiles with vehicle running on turnout which has tongue rails and crossing rails. This paper shows the analysis method and the results of dynamic simulation of the vehicle running on a turnout at high speed considering longitudinal variation of rail profiles.
