Abstract
The Free vibration response of the Railway Bogie is an important area in the design of the Rail coach and to improve the ride comfort of the passengers. In this study, the railway Bogie considered is Fabric Italina de Automobil Torino, Switzerland (FIAT) Bogie of Linke Hofmann Busch (LHB) AC 3 Tier coach. This paper aims at the study of the vibration response of a FIAT Bogie of coach subjected to free vibration and to find the Natural frequencies of vibration and mode shapes. The geometric model FIAT Bogie and other related components is modelled using Solid works 2016 package and analyzed using numerical simulation package ANSYS 19.1 Workbench. The Primary and Secondary suspension systems and various dampers used in FE analysis are modelled as spring and damper elements respectively. In this work, free vibration analysis or modal analysis of the FIAT railway bogie is carried out to extract the first few modes of vibration. The Natural frequencies obtained along with the corresponding mode shapes of the bogie show that they are within the permissible range specified by the standards of railway department also for better ride comfort of the passenger.
