Abstract

Friction springs have different characteristics while loading and un-loading. Because of these characteristics, they are utilized in impact systems. In this paper, the design of a recoil system with friction springs for use in a machine gun system has been presented. In order to determine the stiffness of a friction spring, equations of motion for a simple gun model with a recoil system have been derived. The impulse balance scheme has been adopted. On the basis of simulation results, the diameter of the friction spring has been determined.

마찰 스프링은 부하가 가해질 때와 가해지지 않을 때 서로 다른 특성을 가지고 있다. 마찰스프링의 이러한 특성으로 인해 충격 시스템에 주로 사용된다. 본 논문에서는 마찰 스프링을 포함한 발사장치의 주퇴복좌기 설계 연구가 수행되었다. 마찰 스프링의 강성을 결정하기 위해서는 충격량과 운동량 관계를 고려한 단순한 발사장치 모델의 운동방정식이 개발되었다. 발사장치의 동적 거동시뮬레이션 결과에 기초하여, 주퇴복좌 시스템의 마찰 스프링의 지름을 결정하였다.
