Abstract

This paper describes the design of dual-structured and thick-walled cylinder made of composites and special steel. The structure of special steel and composites reduce the weight of a product maintaining its property which is proper to the characteristics. Hence they are used in the fields, such as various ground weapons, aerospace and sports industries, where high elasticity and low weight are required. Thus in this study, the analysis was conducted to find the most proper composite application method changing its types and angle of laminates for the design. Through the comparison of the results, we suggest the method for composite application which is the most appropriate to the designing purpose of this study.

본 연구에서는 특수강과 복합재료를 사용한 이중구조 실린더의 설계를 위한 해석에 대해서 기술하였다. 특수강과 복합재의 이중구조는 제품의 특성에 적합한 물성을 유지하면서도 무게를 절감해 줄 수 있으며, 이로 인해 고탄성 저중량을 필요로 하는 각종 지상무기 산업분야와 항공분야, 스포츠 관련 분야 등에 점차 확대 적용되고 있다. 따라서 본 연구에서는 하나의 설계에 복합재의 적층각, 종류 등을 바꾸어 가며 이중구조의 설계에 가장 적합한 복합재 적용 방법을 찾기 위해 해석을 실시하였다. 또한 해석의 결과 값들의 비교를 통해 본 연구 설계목표에 가장 알맞은 복합재 적용 방법을 제시하였다.
