Structural Strength and Fatigue Life Calculation of Y32 Bogie Frame by Finite Element Method

Abstract

Bogie is a chassis carrying wheels, suspension system, brakes and attached under the railway vehicles for running. Generally two pieces of bogies used for one passenger coach and a railway vehicle consists of several coaches. Bogies are critical components of a railway vehicle because of being running components. So during the design process there are a few standards must be obeyed for running at international railways. These standards can be detailed like methods of specifying structural requirements of bogie frames [1], wheelsets and bogies, wheelsets [2], draw gear and screw coupling [3], ride comfort for passengers, measurement and evaluation [4] etc. Because of being an important piece of a railway vehicle, there are so many studies about bogies. M. Kassner [5], S. Shukla [6], Lu Yao-hui [7] studied about simulation of bogies structural strength, fatigue life and compared them with experimental results. In this study a structural and fatigue analysis of Y32 bogie were examined according to TS EN 13749 standard. The static structural and fatigue life analysis were performed respectively. It was seen that Y32 bogie achieved the obligations specified at the TS EN 13749 standard.
