Experimental Evaluation of Metro Rail Bogie Frame through Bench Testing

Bogie frame is a main skeleton and structural member in railway system which is carrying all the loads such as Suspensions,Axles,wheels, car body, Motor, Gear box etc. The frame is subjected the exceptional and service stresses in Vertical, Longitudinal, Lateral and twist directions throughout the service life which should be withstand for a life span of 30 years without failure. The purpose of this project is to determine the Structural integrity of the Metro rail bogie frame in consideration with EN13749 standard .This paper is the outcome of bench testing of metro rail bogie frame with the application of multiaxial loading in static and dynamic campaign through which stress data is collected with strain gauge sensors and correlated with the FEA results at design stage. This helps to verify and evaluate the design and validate the quality of metro rail frame as per the requirement specified in EN13749 European standard in early design stages.
