PERMISSIBLE MAXIMUM VALUES FOR THE Y- AND Q- FORCES AS WELL AS THE RATIO Y/Q. EFFECT OF THE SPACING OF CONSECUTIVE AXLES ON THE MAXIMUM PERMISSIBLE VALUE OF LATERAL LOAD FROM THE STANDPOINT OF TRACK DISPLACEMENT FIRST PART: TESTS WITH A TWO-AXLED WAGON

The report covers the study programme and the results of the first stage of the tests carried out with a view to determining the effect of the distance between consecutive axles on the maximum permissible value of the lateral load applied by a wheelset from the point of view of the danger of track displacement. This first stage related to static tests at low speed (6 - 80 km/h) with a two-axled wagon with a large wheelbase, only one of whose wheelsets applies a lateral load to a track which has been deconsolidated as a result of a levelling operation. The results obtained with such a vehicle and track suggest a limit as defined in the report of about (10 plus P/3) kN, P being the axleload.
