코킹 프레스 체결의 접합부 강도 및 피로수명에 대한 연구

Caulking joining has merit to easily manufacture and assemble, and to decrease the cost of product. However, though the design on caulking process is very important inorder to obtain the satisfactory strength, the research on caulking joining is insufficient. Therefore, in this paper, the tensile and fatigue test for an evaluation of caulking part of drum of washing machine were conducted. Also, the caulking process was simulated by finite element analysis and the residual stress of caulking part was evaluated.
