Control arm is the structural component that pivots on two places. One end of the control arm is attached to the body frame and the other end is attached to the steering knuckle. The former research proposed the structural design by applying optimization technique with aluminum alloy. This study suggests a durability test method on the developed upper control arm to validate the analysis results. The durability analysis results of the developed control arm by using MSC Fatigue is confirmed to be close to infinite life. The weak model of developed control arm which occurs to finite life is made to perform the durability test and the zig design is developed in this process.
