Abstract

Recoil system for 40mm automatic gun is a device developed to absorb the shock of explosion. It is impossible to conduct pinpoint strike due to recoil if very high explosive shock, which is generated when an automatic gun fires shells, can't be absorbed. This study covers development and verification of analysis model for recoil system by utilizing a multi-domain software. The research process is as in the following. First, an analysis model is developed to verify damping characteristics through understanding of design intention. Second, environment which is identical to a field test is set up on analysis tool after putting explosive force that is measured through the test into the analysis model. Finally, the analysis model for recoil system using the multi-domain software is verified if it has effectiveness with a comparison between internal pressure of the recoil system along with displacement of gun barrel and the field test result.

자동포용 주퇴복좌장치는 사격충격을 흡수하기 위한 목적으로 개발된 장치이다. 만약 자동포에서 탄자가 발사 될 때 발생하는 매우 높은 수준의 사격충격을 흡수하지 못한다면 반동에 의하여 정밀한 타격은 불가능해진다. 본 연구에서는 이러한 역할을 하는 주퇴복좌장치의 해석모델을 멀티도메인 소프트웨어를 활용하여 개발하고 검증하는 것을 다룬다. 연구의 진행과정은 다음과 같다. 우선 설계의도를 파악하여 해석모델을 개발하고 기본적인 감쇠특성을 확인한다. 그리고 필드테스트에서 얻은 사격충격력을 해석모델에 부여하여 필드테스트와 동일한 환경을 해석도구 상에 구축한다. 최종적으로 주퇴복좌장치의 내부압력과 포신의 변위를 필드테스트 결과와 비교하여 멀티도메인 소프트웨어를 활용한 주퇴복좌장치의 해석모델이 유효성을 갖는지를 검증한다.
