함정용 2축 안정화 장치의 다물체 동역학 및 위치 제어 해석

Abstract

A naval shipboard inevitably movies in a pitch and roll direction under the influence of wave and wind in the sea. As a result, the shipboard gets in a continuous turning motion back/front and right/left. And the shipboard is also constantly exposed to many different kinds of disturbance signals including the vibrations of various frequencies from the internal equipments and their vibrations, strong waves, and impact from explosion. This paper formulates multi-body dynamic models similar to an actual system and simulates the pitch/roll positions of a 2-axes gimbals with PI controller for consecutive behavior of a naval shipboard including disturbance.

함정은 해상 운용 시 파도 및 바람의 영향으로 인하여 Pitch Roll 방향으로 운동이 불가피하다. 따라서 함정은 전 후 좌우로 연속적으로 회전 운동을 한다. 그리고 함정은 내부 장비들의 가진에 의한 다양한 주파수의 진동과 강한 파도, 폭발에 의한 충격 등의 외란 신호에 항상 노출되어 있다. 본 논문에서는 실제 시스템과 유사한 전산해석 모델을 작성한 후 외란 신호를 포함한 함정의 연속적인 거동에 대하여 2축 안정화 장치 의 동적 거동 및 위치 제어 전산해석을 수행한다.
