| Abstract: | Using the finite element method,applying a mechanical model close to the welded turnout,this article has made the analysis to the force and deformation of the welded turnout on the basis of comprehensive consideration of effects of sleeper,fastening and track resistence.A computer program has been worked out and a kind of welded turnout is caculated as an example , the results are agreeable to the experiment . It has provided a calculating and theoretical basis for laying welded turnout in our country. |
