Bibliography

- Describes the forces and moments to be taken into account with reference to masses, traction and braking conditions; - Provides the stress calculation method for axles with outside axle journals; - Describes the maximum permissible stresses to be assumed in calculations for steel grade EA1N defined in EN 13261; - Explains the method for determination of the maximum permissible stresses for other steel grades; and - Ascertains the diameters for the various sections of the axle and recommends the preferred shapes and transitions to ensure adequate service performance.
