초록

이 연구는 1050MPa급 경량 연성 주철 주관류 컨트롤 암을 개발하기 위한 첫 해의 결과를 보여줍니다. 첫째, 최적 설계 구조를 위한 레이아웃 설계 및 구성 요소 개발, 그리고 컨트롤 암 강성과 최적 구조 디자인 및 강건성 설계를 통해 예상 응력을 제어하는 중점 영역의 강건성을 달성합니다. 둘째, 높은 강성과 고성능 경량 구조를 반영하는 컨트롤 암을 개발합니다. 중공을 통해 소비자가 요구하는 설계와 강성을 충족시키기 위해 개발된 컨트롤 암은 코어 제작 공정을 개발합니다. 셋째, 최적의 합금 조성과 열처리 방법을 통해 철 합금 (Cu, Ni, Mo)의 양과 Austempered 열처리 및 조화 상태를 도출합니다. 넷째, 저강도, 고강성 구성 요소 개발을 위해 최적의 성형기술 개발을 통해 최적의 주조 기술 개발로 이어지는 구성 요소 개발을 위한 높은 강도의 주조 형성 기술을 개발하기 위한 시도를 합니다.

This study is shown the result of the first year to develop an export 1050MPa-class lightweight ductile iron castings Austempered control arm through the research process to obtain the following results. First, the structure of the optimal design Layout design and development of the component, and then achieve them through the Control Arm rigidity and optimal structure design and robust design of the focus areas of the expected stress Control Arm. Second, to develop a Control Arm reflects the high rigidity and high performance lightweight structures. Control Arm them developed to meet the design and rigidity as required by the consumer through the hollow, and to develop a process for the Core. Third, through optimum alloy composition and heat treatment methods will be derived to derive the amount of iron alloy (Cu, Ni, Mo) and Austempered heat treated and tempered condition. Fourth, through the development of optimum molding technology development component to develop the optimum ADI for the low-stiffness, high-rigidity component development, it attempts to develop a high-strength casting forming technology..
