PERMISSIBLE LIMIT VALUES FOR THE Y AND Q FORCES AND DERAILMENT CRITERIA. PERMISSIBLE MAXIMUM VALUES FOR THE Y AND Q FORCES FROM THE POINT OF VIEW OF RAIL STRESSES AS A FUNCTION OF DIFFERENT PARAMETERS
Using the calculation methods described in C 138/RP 2 and in Technical Document DT 104, the influence of the vertical and horizontal stiffness of the track, the sleeper spacing, adjacent axles and rail profile has been shown by means of isobars. The calculation results have been compared with measurements. Other parameters influencing the permissible maximum values for the Y and Q forces are mentioned.
