Abstract

Nowadays, the railway vehicle system are widely use and with the rapid development of railway use, vibration control to maintain stability, safety and improvement the level of passenger discomfort become the crucial part of research. This study focus on the semi-active suspension system and the 3 Degree of freedom ( DOF ) are developed using Newton second law which consist of two vertical dampers and springs, and a set of lateral spring and damper in lateral direction. The stability augmentation system (SAS) and PD-SAS are introduced in this study in order to reduce the unwanted motion. The response of the vehicle performance are investigated under step and sinusoidal track irregularity. The response of semi-active system are compared with passive system. Matlab Simulink software has been used in order to investigate and analyse the performance of the railway vehicle model. The simulation results of the study clearly show that the semi-active system are able to improve the performance of the vehicle compared with the passive system.
