THE "CREEP" OF LOCOMOTIVE DRIVING WHEELS (PART I)

The work of various authorities on the experimental and calculated values of tractive creep related to locomotive wheels and railway rails is briefly reviewed. The basic problem discussed is that of a wheel supporting a vertical load rolling on a rail and exerting some value of tractive force to the rail. The contact area between the wheel and the rail was assumed to be of rectangular geometry. The problem is treated as one of plain strain, and the equations of equilibrium in terms of dilation and rotation are given. Further mathematical treatment is given for derivation of expressions for traction, contact stresses, displacement, contact area, the value of surface strain over the locked area, and finally the expression for tractive creep. Diagrams are provided to describe the area of wheel contact and values of tractive force and strain.
