Résumé / Abstract
With several examples, this paper will show why the most significant parameter to be considered at the wheel rail contact is the angle of the tangent plane, function of the transversal relative displacement between wheel and rail (contact angle function, CAF). This parameter is the key point of INRETS methodology for static and dynamic studies of the wheel rail contact in non linear conditions. A practical example is given with switch blades.
