WHEEL-RAIL CONTACT AND FORCES IN CURVES

Abstract

The forces acting on a six-wheel bogie in a curve are compared with those on a four-wheel bogie using the Heumann graphical method of determining forces. It is shown that unless the center or end axles have adequate lateral float, replacing four-wheel bogies by six-wheel, although reducing nominal wheel-load by about 30%, may not reduce the wheel-rail contact forces on the leading wheelsets. The relationship between wheel and rail profiles is discussed, emphasising the need for close control of track gauge and care in matching wheel and rail profiles, particularly on railways where intensive traffic is to be introduced on rail of fairly light section.
