Simulation of Train Load in the Calculation of high-speed Railway Subgrade Dynamic Response

Zhang Bi

Abstract

Load of high-speed railway is a complex issue,which involves many factors such as axle weigh,suspension system,running speed,track structure,railway track smooth and so on.Based on the checkout of test section,taking axle weight,speed and track irregularity into consideration,the sinusoidal excitation function is adopted to simulate the train load.The present essay aims to offer references for the determination of dynamic loads of high speed trains and dynamic responses of sub-grades.
