AN ASSESSMENT OF RAILWAY COACH BOGIE STRESSES UNDER THE INFLUENCE OF RAIL CONSTRUCTION

Abstract

The present work represents a theoretical analysis of the dynamic stresses on a bogie frame using multi-body system (MBS) by applying float frame of reference (FFR) technique. The Dynamic analysis of the railway bogie is applied to study the stresses per time on bogie mainframe using Finite Element Analysis (FEA). Besides the acting weight load of the railway vehicle, the railway track is considered to be the major influencing members in dictating the dynamic forces on the bogie frame of the railway vehicle during running. This dynamic force is expected to be due to the shape of possible irregularities of the track rails or rail. The rails connection is the source of irregularities in this study. The present thesis is composed of six chapters. These chapters cover a survey of previous work in this area of research work and the sequence of application of the analytical and numerical studies. The following chapters showed the stages, methods of solution and results.
