Abstract
Failure in wheels mainly occurs when the train travels on a curved track. When a train runs on a curve maximum load on one wheel. Three types of forces are applied on the wheel while in contact with the rail. Three-dimensional finite element model of the wheel rail interaction is used to investigate the effect of applied loading forces on the wheels. The Interaction between left and right wheel is considered. The wheels are analyzed for the effect of forces on wheels such as Vertical force, Centrifugal force and also Lateral force. This paper also discusses the comparison of safe speed and radius of curvature. The model has been created in Catia software and the finite element analysis has been done in software code and ANSYS. The proposed simulation accurately shows the real geometry and the wheel rail interface. The numerical results show that the speed and radius of curvature are inversely proportional.
Highlights
Rail transportation is considered to be the safest one worldwide
Through upgrading existing ways to analyze the impact of wheel motion on the rail, finite element analysis (FEA) is used as a tool for contact mechanics modelling, assessment, and simulation of the Rail-Wheel contact
Before investigating the vehicle-track system dynamics in curves and the derailment risk, a new technique for modelling the fastener as a clip with a compressive force determined from the tightening torque has been described
Summary
Rail transportation is considered to be the safest one worldwide. Because rail transit is complicated, such tragedies appear to be difficult to entirely eradicate, regardless of the amount of money spent on improving the protection. Due to the constant rise in train speed, further safety is required in rail operations.
