공압피팅은 공압이 사용되는 시스템 및 기계에서 작동유체를 공급하기 위한 유연호스의 접속 및 탈착을 원활히 할 수 있게 하는 공압 시스템의 핵심 요소이다. 공압피팅의 구성요소인 원형 판스프링의 응력분포를 유한요소해석을 통하여 살펴본 결과 원형 판스프링은 공압피팅에 유연호스가 장착 될 때 국부적인 소성변형이 일어나는 것으로 나타났다. 원형 판스프링의 응력집중을 분산시키기 위해 다구찌 실험계획법을 이용하여 최적설계를 수행하였다. 원형 판스프링의 반경, 외측폭, 굽힘각을 주요 설계변수로 설정하였으며 다구찌 실험계획법을 통해 원형 판스프링에 작용하는 최대응력에 폭이 81.3%, 굽힘각이 10.9%, 반경이 1.5%의 기여율을 가짐을 확인하였으며, 최적설계시 초기 형상의 원형 판스프링에 비해 약 4% 정도 응력분산의 효과가 있음을 알 수 있었다
