| Abstract: | Appliying to finite element software ANSYS APDL general of parameterized modeling technique, a finite element model of the NO. 18 seamless turnout is built up by using the finite element method. The bending additional longitudinal force and displacement of seamless turnout on simply supported beam bridge and on continuous beam bridge are both analyzed, the rule of the distribution are also summarized. The results can be used to guide the design of the seamless turnout on the bridge. |
