WHEELSETS WITH ASSEMBLED AXLEBOXES: DESIGN, MAINTENANCE AND STANDARDISATION. CALCULATION OF AXLES, PART 1: FORCES AND MOMENTS TO BE TAKEN INTO CONSIDERATION; RECOMMENDED GEOMETRIC FORMS AND SURFACE CONDITIONS

Commencing from the axle calculation methods used by different railway administrations (or by axle manufacturers) and the measurements made during line tests, the report proposes vertical and lateral forces to be allowed for in the calculation of wagon-axles. The incidence of the forces introduced by braking (on the wheel or with axle mounted discs) has also been examined. In taking the experience of some major administrations as a basis (experimental studies and service results) the report also proposes some recommendations on the subject of geometric forms to be adopted for the different constituent parts of an axle (relative dimensions and transitions between sections of different diameter) and the preferred surface conditions on the different parts. The complete axle calculation method will form the subject of a comprehensive report which will include the recommendations of the present report.
