Analyze the Effect of Slip Angle on Fatigue Life of Wheel Rim of Passenger Car by Using Radial Fatigue Testing

Mr. Sunil N. Yadav, Prof. N. S. Hanamapure

This work aims to investigate the effect of slip angle on stress distribution and fatigue life of wheel rim of passenger car under radial load condition which arises due to off road field area and road unevenness. Finite element analysis (FEA) is carried out by simulating the test conditions to analyze stress distribution and fatigue life of the steel wheel rim of passenger car. Experimental analysis performed by radial fatigue testing machine for evaluation of fatigue life under influence of slip angle. For radial fatigue testing SAE J328 standard is used. This SAE recommended practice provides minimum performance requirements and uniform procedures for fatigue testing of wheels intended for normal highway use and temporary use on passenger cars. In particular, experimental fatigue life calculations of a wheel rim are compared with predictions of a finite element analysis.
