Abstract

This study evaluated the residual stress and deformation for bracket castings of induction motors. Numerical analyses were performed to evaluate the residual stress distributions and displacements of bracket castings after the casting and final machining processes. Based on the analysis results, it was found that bracket casting was satisfied with the internal quality standards during the fabricating processes.

본 연구는 중형 유도전동기 신제품 개발 단계에서 브라켓 주조품 제작시 발생하는 품질문제를 미리 평가하기 위하여 수행한 것으로, 브라켓 주조품의 제작과정인 주조 및 기계가공시 용탕 충진 양상, 결함 발생, 잔류응력 및 변형 등 제품의 품질상태를 수치해석적인 방법을 사용하여 평가하였다. 평가 결과 최종 기계가공 후 브라켓 주조품에 발생하는 잔류응력은 -53~54MPa, 변형량은 최대 1.8mm로 크지 않으며 내부 품질관리 기준에 부합함을 알 수 있었다.
