THE PARAMETERS OF DRIVE MOVEMENT OF THE BRIDGE CRANE DURING START-UP WITH TAKING INTO ACCOUNT ROLLING FRICTION OF THE WHEEL ON RAIL

L. N. Bondarenko, S. V. Raksha

Abstract


An analytical dependence to determine the ratio of rolling friction has been proposed, with account of generally accepted mechanical characteristics of materials and the geometrical parameters of wheel and. This allows specifying the starting time of the bridge crane moving drive and the coefficient of coupling the working wheels with the rail.
