Abstract: Mechanical models and calculationmethods for calculatingthe rail support elasticity coefficients of fixed-frog simple turnouts and movable point rail simple turnouts are proposed. Apractical computer program is designed. With the Chinese No.12 fixed-frog and movable point rail speeding-up turnouts of 60 kg/m rail having been analyzed, the variation rule of vertical rigidity of the turnouts along the longitudinal direction of track are exhibited.
