| Abstract: | Mechanical models based on the finite element method are established to evaluate the longitudinal force and displacement of welded turnouts.Using the Chinese No.9 turnout with rigid frog as an example,the influences of the link style of two welded turnouts on the rail displacements and longitudinal forces are analyzed. Contrast with the simple turnout,conclude the force and deformation changing.law of welded turnouts. |
