초기소재 형상 및 위치가 고정 스크롤 알루미늄 열간단조 금형 수명에 미치는 영향 분석

다국어 초록 (Multilingual Abstract)

In this paper, effect of initial material geometry and position on die stress is investigated using finite element analysis. Various geometries and positions of initial workpiece are considered to reveal their effect on the die stress, especially in the region where tensile stress is exerted, which is supposed to cause premature die fracture. It has been found that proper geometry of initial workpiece can increase die life much longer than expected because it can reduce the die stress in tension by about 34 percent only with radius of initial material reduced and its center fixed near the point where premature die fracture occurred. An optimized tilted material can also reduce the die stress in tension by about 25 percent compared with the flat material with same radius.
