Abstract

Abstract

The regularity of longitudinal force transmission of welded turnouts with different types of frog and heel is investigated, and the effects of frogs and heels on the force and displacement of the parts of a welded turnout are discussed. The types of frog and heel dicussed include rigid frog, long-wing movable-point frog and short-wing movable-point frog for the former and spacer block and spacing restricting device for the latter. The research result shows that combination of the long-wing movable-point frog and the spacing restricting device is a more reasonable structure of welded turnouts.
- jointless track,
- temperature force,
- displacement
