| Abstract: | According to the theory
of equivalent resistance, the expand and contract displacement of closure rail, the
additional force of stock rail, the point displacement, and the shear force of bolts of
spacing resticting device at heel were calculated and analyzed in the paper for the 60
kg/m rail, No.12 continuous welded turnout with rigid frog. The results of this paper can
be the theoretical reference for installation design and maintenance of the CWR turnout. |
