Influence of USP on Dynamic Load in Turnout

Popis výsledku v původním jazyce

Recently there were presented the papers dealt with the trial track sections with USP in the Czech Republic. One of these sections is focused on USP application in a turnout. The design of USP arrangement was solved by the help of mathematical model in FEM. The calculations were performed for static load with aim to design a homogeneous vertical stiffness along the turnout length as well as in the part immediately behind the turnout. The next step of research is an implementation of dynamic loads into model analysis. The analytical calculations were accompanied with a simplified mathematical model of a turnout. The vertical deflection was calibrated by using a detail FEM model. The dynamic component force was determined based on vertical rail deflections. After that the analyses were focused on a crossing part. It was investigated a cheaper variant of USP arrangement in which the under sleeper pads are designed only for a few of sleepers under crossing with the same effectivity to the dynamic effects reduction.
