THE BEHAVIOUR OF THE MOTIVE POWER AXLES (WHEELS) ON THE S.N.C.F.

Wheel-set stresses are modified by the action of the strains inherent in service which may be categorized as follows: those affecting the shrinking-on; those which correspond either to vertical effort exerted by the wheel on the rail, essentially cylical, or to the lateral reactions of the rail on the wheel both cyclical and erratic (abnormal shocks); and those set up by a temperature rise, due to braking. The SNCF has tested, both in the laboratory and in service, the diverse stresses as they are linked up with strains. Common damages to wheelsets are described and are shown. Wheel manufacturers are using the test results to enhance wheel design criteria.
