Numerical Prediction of Fatigue Life of Crankshaft

In Automobile manufacturing plant, it was noticed that 7 out of 1000 crankshafts are prone to failure. This work is concentrated to identify the cause of failure in the crankshaft and to improve the fatigue life of the crankshaft by performing parametric study. In parametric study, the crankshaft is designed and analyzed in ANSYS WORKBENCH by varying the fillet radius of journal bearing. The maximum equivalent alternating stress and cycles to failure were predicted in numerical analysis. The cycles to failure are increased by varying the parameter and hence the fatigue life of crankshaft is improved. Citation: R.Keshor Kumar, Thiagarajar College of engineering; T.
