DETERMINAREA REZISTENŢEI LA ROTIREA ŞINEI ÎN PRINDERE ÎN FUNCŢIE DE ÎNCĂRCAREA CARE REVINE UNEI TRAVERSE

Abstract

Usually, the torsional resistance is modeled, by almost all researchers, linear and wihout taking in consideration its changing as a result of the loading which is distribute to a sleeper. In fact, the torsional resistance–rotation characteristic curve can be linear, bi-linear, tri-linear or multi-linear. In this paper is presented one original algorithm for appraisal the influence of the loading which is distribute to a sleeper equipped with K type fastening system. The main application of this algorithm is the adjustment of torsional resistance–rotation values for the CWR track buckling computations in presence of vehicle loadings.
