Material Optimization of Casnub Bogie Frame

Abstract

The bogie frame of a railway is a significant structural component for the support of vehicle loading. In
general, more than 25 years’ durability is needed. Modeling is carried in Pro-E, followed by analysis using COSMOS.
Strength evaluations of the bogie frame were performed to examine the effect of load through the COSMOS. It has been
found that the stress and strain due to the applied loads were critical and sensitive. Even the displacement developed has
been observed. The main aim of this work is to optimize the design of the Casnub bogie of a train in order to identify
suitable material for bogie frame with effective load bearing capacity. Series of analyzing tests were carried by varying
material and also the tests were repeated with self load and additional external load. At the end suitable material has
been suggested.
