Abstract

Helical compression springs have been widely used in industries. The springs should be verified through experiment whether the inherent characteristics of the spring can be maintained during the manufacturing process. Considerable time and expense is spent in the manufacturing process. Therefore, in this study, the structural integrity evaluation of a spring was conducted using linear static structural analysis. Verification and comparison of the experimental data were carried out using a variety of international industrial standards with the intent to prove the validity of this study. The spring model did not consider coil ends. As a result of conducting the structural analysis, the quality of the mesh was improved and the time needed to create an analytical model was reduced. The study indicated that Poisson's ratio had little influence on the result of the structural analysis. Additionally, the possibility of verifying the structural integrity evaluation by structural analysis was confirmed.

산업에서 널리 사용되고 있는 압축 원통 코일 스프링은 제작 시 스프링 고유의 특성을 유지할 수 있는지 실험을 통해 검증해야 한다. 이 과정에서 많은 시간과 비용을 소비한다. 따라서 본 연구에서는 선형 정적 구조 해석 방법을 이용하여 스프링의 구조 건전성 평가를 수행하였다. 본 연구의 타당성을 입증할 목적으로 설계 규격 및 각종 국제적 평가 규격에 의한 실험적 방법과의 비교 및 검증을 수행하였다. 양 끝단 처리를 하지 않은 스프링 형상을 사용하여 구조 해석을 수행한 결과, 해석 모형 제작에 필요한 시간은 절감하고 격자의 질은 향상할 수 있었다. 푸아송 비는 구조 해석 결과에 별다른 영향을 미치지 않았다. 그리고 구조 해석만으로 스프링 구조 건전성을 검증할 수 있는 가능성을 확인하였다.
