Abstract

Anti-aircraft gun system is used for low-level air defense system and has more than twin guns with high firing rate in order to maximize the capability of defense. Gun's vibration and bullet's variance has a critical effect on accuracy and hit probability of weapon system such as anti-aircraft gun system with high firing rate. Typical mechanism to reduce the amount of vibration and shock during gun-fire process is very important design factor. In this paper, the suspension characteristics of the vehicle are studied for the improvement of isolating performance of gun firing system with high firing rate. Gun fire test for the vehicle is conducted and computational models using Recurdyn and Adams are created based on test results. Through this study, results of computational analysis are compared with the real test results, which includes type, location and quantity of suspension and gun mechanism are selected for anti-aircraft gun. From the result of this study, we could make basic design and consider the proper component of the system such as suspension and gun spring.

비행기 방어용 대공포는 저고도 방어체계로 사용되고 있으며, 방어능력 극대화를 위해 대부분 고발사율 대공포를 두개 이상 탑재하여 교전 시 명중률을 높이고 있다. 고 발사율 대공포의 경우, 포열진동 및 탄의 불균형 분산은 정확한 조준사격 및 명중률에 아주 결정적인 영향을 미치게 된다. 따라서 사격 진동 및 충격량을 감소하는 구조는 대공포 체계에서는 주요 설계 대상이다. 본 연구에서는 차량의 현가장치 특성에 따라 고발사율 대공포 체계에서 발사시스템의 진동충격으로부터 차단하는 능력을 향상시키고, Recurdyn 과 Adams 를 이용한 동적 거동해석과 실 사격 시험결과를 비교하여 명중률에 영향을 미치는 현가 형태, 위치 및 수량에 따른 체계 자세 흔들림을 예측하였다. 본 연구를 통하여 대공포에 적합한 현가장치와 포 스프링 등과 같은 구성품을 선정할 수 있는 기초연구를 수행하였다.
