| 초록 |
Welding is widely used in the automobile industry, but suspension parts are exposed to various load conditions and are vulnerable to fatigue damage in the welding part. Durability problems occur in areas where gas metal arc welding of subframes and arms is applied. In this study, the fatigue characteristics depending on the shape of weld and the load direction were analyzed through specimen tests for the T-joint fillet welding structure. The fatigue limit load was compared 300,000 cycles times for each load condition of the welding part in the tensile, shear, and ± bending directions. A method for robust design depending on the load direction designing suspension parts was identified. And the durability of the double-sided welding in T-fillet joints was compared with the single-sided welding. |
