Modal and Static Analysis of Luggage Rack Systems Used in Mumbai Suburban Railway Trains

Abstract

In this study, the authors have made an attempt to perform a numerical investigation of a luggage rack system, which is used in Mumbai suburban railway trains. The first part of the investigation focuses on modal analysis to calculate the natural frequencies of the system, which then is studied in comparison with the phenomenon of hunting oscillation observed in railway trains. The second part of the exercise focuses on the stress-strain behavior of the system, total deformation, stress, and strain under a given load. It is observed that the given system performs safely for the given practical load, and also for the excitation frequencies observed in trains.
