<br/><br/> The present work represents an investigation 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). The weight load of the railway vehicle, the railway track and the vehicles suspension system are considered to be the major influencing members in dictating the dynamic forces on the bogie frame during running. This dynamic force is expected to be due to the shape of possible irregularities of the track rails and/or rails connection.  Results concluded that the stiffness of the suspension system is of a prime importance in dictating the final stresses in bogie frame structure
