Abstract
To ensure the safety and stability of high speed railway vehicles (HSRV), the study of lateral dynamics of railway vehicles is significant. This paper presents a heuristic non-linear creep model and linear creep model to investigate the effect of suspension parameter and wheel conicity on lateral dynamics of HSRV as suspension elements and wheel conicity affect the passenger comfort, stability and hunting behaviours of HSRV. For the analysis, a 31-DOF full car model consisting of a car body, two bogies and two wheelsets for each bogie is developed using the bondgraph technique. Parametric variation in the suspension parameter has been made to study the effect on critical hunting speed. From the analysis, it has been observed that primary suspension elements have a more significant influence on vehicle stability. A correlation between primary suspension elements and wheel conicity with critical velocity has been tried to establish. From the study, it has been observed that critical velocity increases with increasing the value of the suspension parameter, but its value decreases with increasing wheel conicity.
