Modeling and Cyclic Stress Analysis of Automotive Alloy Wheel Rim

Abstract

Aluminum Alloy wheels has superior thermal conductivity. (>150 watts per kelvin per meter) than Steel (45 watts per kelvin per meter) ,generally lighter offering more structural strength, improve handling by reducing unsprung mass, allowing suspension to follow the terrain more closely and improve grip. Alloy wheels offer better corrosion resistance, do not rust internally like steel wheels and thus last the life of a vehicle. This paper presents the modeling and simulation results of modeling and cyclic stresses analysis of wheel rim. Now a day’s light alloys wheel materials are used in vehicles. To improve the quality of wheel rim evaluate in the cyclic stress life of wheel proposed in this project.  In this paper we designed the rim from the Prevailing dimensions by Pro-E Solid modeling software which one is suitable for wagons wheel rim material can be analyzed by using NX NASTRAN software. Main aim is to reduce the unplanned brake failure due to overheating Lighter wheels can improve hold by reducing unsprung mass, Countenancing suspension to survey the terrain more closely and thus improve grip, conversely not all alloy wheels are lighter than their steel equivalents.  Wheels are endangered to a high freight. Therefore, it is obligatory to observe a wheel for both strength and cyclic stress struggle, Further we can do optimization of material thickness to moderate the material consumption. Supplementary we can improve life of component by using Progressive cyclic stress strain life approach.
