Calculation of wheel impact force due to interaction between vehicle and a turnout
It is known that railway turnouts demand more maintenance than other parts of the railway track net-work due to large impact loads generated by the variation of wheel-rail contact conditions along the turnout and through the crossing. A method using VAMPIRE modelling to determine the wheel impact forces due to passing turnout has been developed and presented in this paper. The simulation shows that both turnout curve and crossing have significant effect on he wheel impact forces.
