The subject matter of the article is the methods for determining the safety parameters to prevent wheel derailment. The object of the study is the interaction of a rail track and rolling stock. The goal of the paper is to study of approaches that are used... see more

The main intention of this research work is to study the derailment response of high-speed railway vehicles (HSRV) cruising on a curved track. In previous research work, a lower degree of freedom (DOF) has been considered for the derailment analysis which... see more

The work considers three stages of derailment process, which are the flange climbing the railhead, the wheelset falling down from the rail and the wheelset motion over the sleepers. Numerical, roller rig and natural experiments were carried out for each s... see more

This article offers the methods of calculation of the start points of contact during wheel set-rails family interaction. The states of wheel set are investigated; the types of possible specific wheel set states, turning-over of rolling stock elements and ... see more

A graphical representation of the Nadal’s criterion is proposed in the paper.

In this study, the locomotive and the turnout were simulated with three-dimensional models. The purpose of this study is prediction the derailment phenomenon of the locomotive running on the turnout in Vietnam. Multi-body simulations were implemented by S... see more
