실차하중 조건의 내구해석을 통한 알루미늄 컨트롤 암의 성능 개선

The use of aluminum control arm is on the increase to reduce vehicle weight and improve fuel efficiency. In this paper, durability performance of aluminum lower control arm is examined with fatigue analysis using vehicle road load data. Analysis was conducted by quasi-static fatigue analysis method. Analysis results was compared to vehicle test result. Design improvement of lower control arm is suggested to increase durability performance.
