| Abstract: | A model is proposed for calculating the flexural rigidity of rail joints. The calculation formulas for the stability of the track with frozen joints are deduced. The influences of some parameters, such as joint resistance, installed rail gap and radius of the curve, on the stability of tracks with frozen joints are analyzed and the critical forces in different conditions are listed with a table. |
