VERFAHREN ZUR ERMITTLUNG DER NEUTRALTEMPERATUR IN LANGGESTRECKTEN WERKSTÜCKEN
The invention pertains to a method for respectively determining the neutral temperature or the stressfree state in a rail section (1), wherein an ultrasonic signal is coupled into a representative volume of the rail profile perpendicular to its longitudinal direction, wherein the volume is subjected to stresses in the longitudinal direction of the rail section (1), wherein the stresses are measured, wherein an ultrasonic signal influenced by these stresses is decoupled, wherein a function describing the functional dependence of the decoupled ultrasonic signal on the introduced stress is determined, and wherein the stressfree state is determined based on the course of this function.
