- W335745949 abstract "This chapter reviews the investigations of the dynamic modulus of elasticity of a track in ballast with regard to high speeds. The increase in axle load and travelling speed is limited by the bending stresses at the edge of the rail base as a result of dynamic loads together with guide forces and thus upon the fatigue strength and the geometrical integrity of the rail. Of particular significance are the stresses in the contact surface wheel/rail, which depend upon the material of the wheel and the rail, and upon the relation of wheel load Q to wheel diameter D (Q/D). To avoid shelling and wheel rim break, the values of Qstatic (in kp) to wheel diameter D (in mm), should not exceed 12 for rail and wheel qualities of 70 to 80 kp/mm, or 13 to 15 for materials of higher tensile strength. Values Q/D of 16 to 18 is disadvantageous for rails and wheel rim unless a steel of 110 kp/mm2 is used. The third dependence consists in an adequate ballast height together with sufficiently large pressure transfer surface from the tie to the ballast and to the subgrade." @default.
