DETERMINATION OF THE SNAKING EFFORT IN TRACK LAID WITH LONG WELDED RAILS BY MEANS OF A NON-LINEAR CALCULATION

The author describes a method to ascertain, with the assistance of an electronic computer, the axial effort due to snaking in a track laid with long welded rails. In these calculations, the influence of the lateral resistance and that of the angular rigidity can be introduced in their true nonlinear form, so accurately that the stress under which snaking occurs can be determined exactly. It is necessary to establish by measurements the lateral resistance and the angular rigidity. After this has been done, the admissible value of the preliminary deformation, free of stress, of a track with long welded rails can be calculated fairly rapidly. Provisionally we can affirm that the critical wave length will be considerably shorter than that obtained by the methods of calculation previously suggested.
