The present invention relates to an underwater impact test using airbag inflators. Conventional underwater impact tests use air guns to generate shock waves, but there is a disadvantage in that the shock waves are concentrated in low frequencies compared to using explosives. To address this issue, in the present invention, multiple airbag inflators are used to form underwater shock waves with a wide frequency band. In addition, the airbag inflators used in the present invention may have various initial pressures, and a grid in which the airbag inflators are fixedly disposed may be formed to correspond to a curvature of a hull. A distance between the hull and the airbag inflators is adjusted to form plane waves for simulating an actual explosive shockwave, and the plane waves may be formed by adjusting a blasting time of each of the airbag inflators.

    본 발명은 에어백 인플레이터를 이용한 수중충격시험에 관한 것이다. 기존 수중충격시험은 에어건을 이용하여 충격파를 형성하였으나 폭약에 비해 저주파에 집중되어 있는 단점이 있어, 다수의 에어백 인플레이터를 이용하여 넓은 영역의 주파수대를 갖는 수중 충격파를 형성하고자 한다. 또한, 이용되는 에어백 인플레이터는 다양한 초기 압력을 가질 수 있으며, 에어백 인플레이터가 고정 배치되는 그리드는 선체의 곡면에 대응되도록 형성될 수 있다. 실제 폭약 충격파를 모사하기 위해 평면파를 형성하도록, 선체와 에어백 인플레이터의 간격을 조절하며, 각 에어백 인플레이터에 발파시간을 조절하여 평면파를 형성할 수 있다.
