DYNAMIC ANALYSIS OF RAIL-WHEEL INTERACTION FOR FREIGHT WAGON

Abstract

This report deals with the dynamic analysis of rail-wheel interaction. The model has been developed for dynamic analysis of freight railway wagon. A solid model has been developed using solid works on the basis of standard rail profile (UIC-60) and wheel profile (S-1002). The freight wagon incorporated is widely used BOXN25 wagon and the bogie which is used is CASNUB bogie which is mainly used for freight wagons. Finite Element analysis (FEA) of the solid model has to be done using ANSYS software. In this anaysis, The values of natural frequencies has been calculated using Block Lancoz solver which is a recurssive solver. Mode shapes and the values of the maximum and minimum deformation has also been calculated. During the analysis the body of the wagon has been considered flexible.
