회전기 shaft의 rib 용접부 피로수명 평가
Fatigue life Evaluation of Rib Weldment for Generator Shaft
- 발행 : 2006.05.01
초록
The purpose of this study is to evaluate the fatigue life at the rib weldment of generator shaft. In order to do it, the stress distributions at the weldment under design loading condition were evaluated using FEA and analytical approach. The fatigue strengths of the as welded and toe machined rib specimen were estimated using 3-points bending fatigue test. Based on the fatigue test results, the S-N curve far the rib weldment of the generator shaft with post treatment was established.
