RIDE INDEX PERFORMANCES OF HIGH-SPEED RAILWAY TRAINS
Railway trains are becoming one of the important transportations in nowadays era due to their effective means of travelling from one place to another place. Therefore, many researchers work toward increasing the ride quality and performance of railway vehicles. The aim of this paper is to analyze the ride index of three different trains which are French Thalys Y230A, German ICE 3, and China CRH2 trains through simulation. The model focuses on six degrees of freedom (6DOF) and the Sperling Index Method is used to determine the ride index for each train. Three elements such as mass, spring and damper are connected in series and modelled in MATLAB/Simulink. The system can be used to simulate the dynamic behavior of the mass under varied conditions, such as a variety of initial conditions, different spring and damping constants, and various external forces. The results obtained from the graph can be concluded as the ride index performances of the trains.
