| Abstract: | A mechanical model and its calculation method are advanced for calculating the variation regularity of load on the rails of the close contact section between switch point and stock rail. Combined with the No. 12 speeding up turnout of 60 kg/m rail in China, the variation regularity of load on the switch is analyzed. Some effective measures, such as setting rail cant and optimizing the top surface gradient, etc., are put forward to decrease the flexural stress of the switch rail. |
