초록

This study investigates fatigue life and possibility damaged at disk brake of automobile by the simulation of fatigue analysis. Among nonconstant fatigue loads, the case of ‘SAE Bracket History’ which is the severest at the variation of load tends to be most unstable. The case of ‘Sample History’ which becomes slower at the variation of load tends to be most stable. The value of maximum relative damage in case of ‘SAE Bracket History’ is occurred near the average stress ‘0’ and this case can be shown to have the possibility to affect more damage than another case. As the result of this study is applied to automobile parts with non constant loads, durability can be improved during drive by preventing any damage.
