This paper presents various aspects of using active vertical secondary suspension in arail vehicle to improve ride comfort. Dynamic control of the vertical and roll modes ofthe carbody is achieved by means of actuators replacing the conventional vertical dampersin the secondary suspension. Active damping improves vertical ride comfort, compared toa passive system. Besides dynamic control, the actuators are able to generate quasi-staticroll control between the carbody and bogies in curves. This allows for higher speeds incurves, without negatively affecting ride comfort. Furthermore, the anti-roll bar is removedto reduce the number of components.
