Abstract [en]

This paper presents various aspects of using active vertical secondary suspension in a rail vehicle to improve ridecomfort. Dynamic control of the vertical and roll modes of the carbody is achieved by means of actuators replacingthe conventional vertical dampers in the secondary suspension. Active damping improves vertical ride comfort,compared to a passive system. Besides dynamic control, the actuators are able to generate quasi-static roll controlbetween the carbody and bogies in curves. This allows for higher speeds in curves, without negatively affecting ridecomfort.
