This project looks into the performance of stabilizer bar with respect to their stress variations at corner bends and weight optimization. The focus is on the stress concentration at the corner bends of a stabilizer bar, that is designed for an automotive vehicle, which is reduced by optimizing the shape of the critical regions in two types of stabilizer bars, one is solid and other is hollow. In order to do this, parameters which constitute the geometry of the stress concentrated regions are determined. The effect of these parameters on stress concentration is evaluated by using Design of Experiments (DOE) approach and parametric correlations. Possible design options and their corresponding mass and maximum equivalent stress values are obtained by using FiniteElement Analysis. The results are assessed by means of response surfaces generated by FEA software. FE analyses showed that it is possible to decrease the maximum equivalent stress at the critical regions for solid and hollow stabilizer bar by 11% and 12% respectively with a mass increase of 3.75% and 3.45% respectively. Transition form that gives optimum stress concentration is determined. %K Stabilizer Bar %K Stress Concentration %K Design of Experiments Method %K Parametric Optimization %K Finite Element Analysis. %U http://www.ijrame.com/vol1issue4/v1i402.pdf
