| Abstract: | This paper presents a kind of effective testing method of the axial temperature force of the continuous welded rail track when the temperature changes. The new theory and principle are presented. The mechanical model of the continuous welded rail is established to investigate the changing law of the lateral force and the effect displacement when the temperature changes. Parameter amendment is done in association with the calibration experiment. Accurate testing of the rail axial temperature force is fulfilled finally. The technology (attains) good effectiveness in practical application. |
| Keywords: | continuous welded rail temperature force of rail calibration experiment displacement method |
