In this paper ,the elastic dynamics model of rail clamping device was established based on kineto-elastic dynamics(KED) method .The elastic displacement of the important nodes of the rail clamping device in different clamping forms and at different installation positions was calculated by nu-merication integration method .The results showed that 18-degree was the most reasonable clamping form and the rail clamping device had better performance when the installation position was far away from the back wheel .
