Friction characteristics of cast iron, two “L-type” and two “K-type” composite brake blocks, used by Indian Railways for tread braking, were obtained experimentally under dry conditions using full scale stop braking experiments. Apparent friction coefficient of brake blocks was seen to depend on brake load, sliding speed, as well as sliding distance. Brake block friction characteristics along with...
Accurate prediction of railway wheel temperatures, for a given running and braking history, is crucial for estimation of service induced thermal stresses which can affect wheel gauge and fatigue crack growth, particularly in tread region. In this work, a three step approach is adopted for estimating wheel temperatures. Firstly, a train running model employing brake block friction, wheel–rail traction-slip,...
