LATERAL STABILITY OF BOGIES AT HIGH SPEEDS. THE INFLUENCE OF A NON-LINEAR TORQUE OF THE BOGIE-BODY SYSTEM

QUERSTABILITAET VON DREHGESTELLEN FUER HOHE GESCHWINDIGKEITEN. DER EINFLUSS EINES NICHTLINEAREN MOMENTS DER VERBINDUNG DREHGESTELL-FAHRZEUGKASTEN

The lateral stability of a bogie at high speeds can be improved by greater torsional stiffness of the roll damper suspension system. The maximum critical speed which can be reached by increasing the roll damping torque is identical to that obtained by a linear analysis which takes into account the torsional stiffness of the suspension system. The maximum critical speed depends on the design features of the bogie and on the wheelset mileage. For a given bogie, the value of the torsional stiffness of the suspension system determines the highest critical speed which can be reached by increasing the amplitude of the roll damping torque.
