Abstract: In this paper the performance of quarter railway suspension system is investigated using MATLAB Simulink under step input condition of the track. Integral Coach Factory (ICF) Bogie is considered for the Analytical Modeling. A linear dynamic system model of quarter ICF Bogie is made and according to the model the mathematical equations are written. The equivalent Simulink model corresponding to the equations are made in MATLAB Simulink. The system is simulated under step input condition of the track to get the performance characteristics such as displacement, velocity and acceleration. The result shows that for the given step input, the major vibrations occurring to the bogie frame and the coach. These vibrations of the ICF Bogie affect the ride comfort of the passenger. The addition of proper controlling element like hydraulic actuator controlled by PID controller to the suspension system of ICF Bogie is suggested in order minimize the vibrations and to achieve the ride comfort for the passenger.
