언벤딩 개념을 이용한 선박용 대형 크랭크 쓰로우 굽힘단조 공법 개발
Development of Bending Process for Crank Throw of Large Marine Engine Using Unbending Concept
초록
The purpose of this study is to develop the optimum shape of blank for the crank throw of large marine engine in order to reduce manufacturing cost and forging defects. The effects of the curvature radius and the height of wing part of blank selected as design variables on the defects and machining margin of final products after forging process were investigated using FEA. Based on the results, the optimum shape for the blank of the crank throw was proposed and verified by experiment.
