Fatigue Life Estimation of Leakage for Excitation and Internal Pressure in Brazed Joints


Article Preview

The study aimed at the fatigue life estimation for leakage of refrigerant used in household air conditioner. The leakage of brazed joints was affected by the manufacturing faults with flaws and service condition which is at the internal pressure and at the excitation. Therefore, the four point bending tests were performed to estimate effects of internal pressure and excitation for the fatigue life of brazed joints. In addition, to investigate effect of internal pressure and excitation on the fatigue life, the orthogonal array table in Design of Experiment is adopted.
