CAVITATION IMPACT REDUCTION STRUCTURE FOR LIQUEFIED NATURAL GAS CARGO CONTAINMENT SYSTEM

摘要

invention cavitation (Cavitation) in due to shock attenuation for liquefied natural gas (LNG) cargo hold cavitation shock attenuation structure and the impact test apparatus and impact test specimens is disclosed. The LNG cargo hold is provided with a first panel mounted to the rear surface of the first wall and the first wall of LNG, which is provided to contact with the surface for storage of LNG. The damping structure of the present invention comprises a plurality of shock-absorbing member is mounted between the first barrier and the first panel so as to absorb the impact load acting on the first wall. Impact absorption members are composed of a fiber mat, a first sheet surface and a second surface sheet which is attached to the surface and the back surface of the fiber mat. By the impact test specimens and impact test apparatus of the present invention can be easily subjected to a test for the impact shock absorbing member that is provided in the cargo hold. ;
