초록

본 논문에서는 유도탄 해치시스템의 스플라인 백래시에 의한 토크 외란에 대하여 실험을 통한 분석을 다룬다. 유도탄 해치시스템은 무거운 해치를 수직으로 상승시키기 위하여 스플라인과 기어열을 사용하고 있다. 해치의 회전축에 적용된 스플라인은 일반적으로 큰 동력전달을 위한 자동차의 구동 부품으로 사용된다. 스플라인은 각도 백래시를 갖고 있으며, 저크를 발생시킨다. 또한 해치 스플라인의 백래시는 해치의 흔들림 발생에 영향을 준다. 스플라인 백래시와 해치의 흔들림은 해치 회전각 및 해치의가속도를 측정함으로써 실험적으로 분석된다. 해치의 흔들림은 짧은 시간동안 육안으로 관찰되며, 회전각의 변화 및 해치 가속도에 의해 측정된다. 해치의 각 변화에 대한 변동형태 및 지속시간은 토크와 유사하며, 백래시에 의한 해치의 흔들림은 토크 외란을 발생시킴을 보여준다.

This paper presents the experimental torque disturbance analysis of a missile hatch system by spline backlash. The missile hatch system uses a spline and gear train for vertical elevation of the heavy hatch. The spline used for the rotation shaft of the hatch is generally used for automotive driving parts that transmit high amounts of power. It has an angular backlash, which results in jerks. Backlash of the hatch spline influences hatch swinging. The spline backlash and hatch swing are experimentally analyzed by measuring the hatch's rotation angle and acceleration. Hatch swing is visually observable for a short period, and it is measured by measuring the rotation angle variation and hatch acceleration. The shape of fluctuation and duration time of hatch angle variation are similar to those of torque. This shows that the hatch swing due to spline backlash generates torque disturbances.
