RAIL VEHICLE ACTIVE SUSPENSIONS FOR LATERAL RIDE AND STABILITY IMPROVEMENT

The potential performance benefits of simple, low power active elements in the lateral secondary, between the truck and carbody is investigated analytically by parametric studies utilizing a fifteen degree of freedom lateral model subject to alignment and cross-level inputs. It is shown that significant improvements in ride quality can be obtained at current operating speeds by using less than 3 kw per truck by sensing lateral carbody accelerations and utilizing lateral force actuators between the truck and carbody. It is concluded that significant ride quality improvements can be achieved by low power, small bandwidth actuators while stability improvement requires increased power and larger bandwidth systems.
