Slamming에 의한 선체의 동적 응답에 관한 연구 = 어선에 적용

다국어 초록 (Multilingual Abstract)

In this paper, the Tuna Long Liner of 48m suffered from serious damages among rough seas, and its main hull was bent at S.S.5(Square Station No.5)by hogging moment. The ship under consideration was in the full load condition, was carring a large amount of caught fish in the fish - hold. If slamming impact pressure occurs at S.S.7, a large hogging moment may appear between S.S.7 and mid - part. The analysis based on the problem of hydro - elastic interaction shows that this damage is caused by hogging moment due to bottom slamming, although, in the case of conventional ships, slamming causes a large sagging moment in the mid - part. Elastic responses such as the whipping vibration are calculated step by step for the ship idealized as a Timoshenko beam, taking account of slamming impact force, which are determined with respect to instantaneous configurations. It is shown that slamming response gives hogging moment enough for the damage in unlucky condition of waves corresponding to the sea state reported.
