초록

Forged aluminum lower arm has been developed to provide weight reduction of suspension parts. It was utilized FEM analysis in design of parts. Prototype parts were producted to two shape & different forging condition. Difference of forging condition was manufacturing process of stock, forging press, forging die, heat treatment condition. As a result, weight reduction of 44%, 38% was achived. Strength and fatigue endurance of forged aluminum lower arm was excellent.
