LATERAL FORCES BETWEEN WHEELS AND RAILS, AN EXPERIMENTAL INVESTIGATION

The paper deals with a new method of measuring continuously the lateral forces between the wheels and the rails over long distances. Fundamental knowledge concerning these forces has been obtained both from studies of the results from short test runs and from statistical assessments of the results from long sections of the Swedish railway network. Since the tests are concerned only with a single locomotive, the results should not be generalized. It is clear, however by means of the individual diagrams of curve forces as well as the statistical evaluation of about 40 curve runs, that the lateral forces between the rails and the wheels of the leading axle are on the whole substantially greater than the resulting force on the permanent way. This factor should be all the more noticed, since the utilized friction coefficient can assume such unexpectedly high values, as is shown from the measurements.
