Numerical analysis of rubber tire/rail contact behavior in road cum rail vehicle under different inflation pressure values using finite element method

Abstract

With the advent of Rail cum road motors there are great demanding situations earlier than Indian railways. Railway Engineers had been for all time interested by the metal wheel-Rail and Rubber tire-Rail contacts. These tiny interfaces govern the dynamic overall performance of avenue cum rail motors via the masses it transmits and, like every high-strain attention sector, it's far subjected to severe damage phenomena. The paper deals with modelling and simulation of the static behaviour of a radial mini truck tire of a proposed road cum rail automobile in touch with rails. The Finite element technique via the ANSYS software program is used to obtain the static behaviour of the rubber tire in contact with rail underneath inflation stress values. The primary goal is to carry out a finite detail analysis and computationally compare the overall performance of a stationary rubber tire along with rim on rails with the aid of changing the inflation stress so that corresponding overall performance parameters like equivalent strain in rubber tire and rims, deformation and call patch of rubber tire are expected and the effect of inflation pressure on these parameters can be understood.
