Description

모형시험용 선박 충격하중 측정 장치Ship impact load measuring device for model test
본 발명은 선박 충격하중 측정 장치에 관한 것으로, 더욱 상세하게는, 파도에 의해 선박의 특정 한 지점에 가해지는 압력과 무게를 동시에 측정할 수 있는 선박 충격하중 측정 장치에 관한 것이다.The present invention relates to a ship impact load measuring apparatus, and more particularly, to a ship impact load measuring apparatus capable of simultaneously measuring the pressure and weight applied to a particular point of the vessel by the waves.
일반적으로, 선박의 항해 또는 정박 시 파도와 선체의 상대운동에 의해 파도가 선체에 부딪히는 현상이 발생한다. 이러한 현상을 슬래밍(SLAMMING) 현상이라고 하며, 이때 선체에 가해지는 힘을 충격하중(SLAMMING LOAD)이라 한다. In general, when the ship is sailing or anchoring, the wave hits the hull due to the relative motion of the wave and the hull. This phenomenon is called slamming, and the force applied to the hull is called slamming load.
선수 또는 선미 부분에 설계치 이상의 충격하중이 발생할 경우, 선체의 구조적 안정성이 급격히 낮아지고, 선체의 외형이 손상될 가능성이 있다.If impact loads exceed the design values are applied to the fore and aft parts, the structural stability of the hull may be drastically lowered and the appearance of the hull may be damaged.
이에 따라, 선체 외형 설계에 있어서, 파도가 선체에 부딪혀 발생되는 충격하중을 감안해 충격하중에 의해 선체가 파손되는 것을 방지하는 것이 바람직하다.Accordingly, in the ship hull design, it is preferable to prevent the hull from being damaged by the impact load in view of the impact load generated when the waves hit the hull.
또한, 실제 선박 및 해양구조물이 건조 되기 전에 모형시험을 통한 충격하중에 대한 평가를 수행하는 것이 바람직하다.In addition, it is advisable to evaluate the impact loads through model tests before actual ships and offshore structures are built.
기존의 모형시험은 선체에 압력센서 또는 로드셀을 장착하고, 계측된 압력 또는 무게를 근거로 충격하중을 산출하였으나, 압력센서 및 로드셀이 일체화되지 못한 구조적인 한계 때문에 동일지점에서 동시에 무게 및 압력을 측정하기 힘들었다.Existing model tests were equipped with a pressure sensor or load cell on the hull and calculated the impact load based on the measured pressure or weight, but simultaneously measured weight and pressure at the same point due to the structural limitation that the pressure sensor and load cell were not integrated. It was hard to do.
이에 상기와 같은 점을 감안하여 발명된 본 발명의 목적은, 파도에 의해 선박의 특정 한 지점에 가해지는 압력과 무게를 동시에 측정할 수 있는 모형시험용 선박 충격하중 측정 장치를 제공하는 것이다.Accordingly, an object of the present invention in view of the above point is to provide a model test ship impact load measuring device capable of simultaneously measuring the pressure and weight applied to a particular point of the ship by the waves.
