碩士 / 國立臺灣大學 / 工程科學及海洋工程學研究所 / 96 / Attention to the marine environmental protection and marine ecology in the world in recent years, to promote the safe of sea going vessel has been regulated strictly. The double bottom and double hull of ships are two types of metal sandwich structures. Due to the progress of laser welding technology and the investment advantage in last years, the European ship industries paid attention to the application of advanced laser welded steel sandwich structures. It has superiority over the traditional stiffened plates and deep girders in uniformly distributed stiffness, light weight, etc. It can be applied to ship and offshore structures, e.g. deck, double hull, double bottom, double bulkhead, and also anti-blast bulkhead. The paper investigate the damage and deformation of the metal sandwich structure subjected to shock loading also the crash worthiness and anti-shock properties of different types of sandwich structure.
In this paper the steel sandwich structures which are possibly used in European ship yard were selected as study cases. The dynamic responses of sandwich structure subjected to low speed and high speed impact will be performed, to observe its crashworthiness against collision and anti-shock characteristics for protection of equipments on board. The six types of steel sandwiches analyzed in the paper are:
a.The double hull structures which are possibly used for ship and offshore structures:The flat-core double hull, The x-core double hull, The y-core double hull.
b.The sandwiches which are possibly used for light structures: The honeycomb sandwich panels, The truss core sandwich panels, The rectangle flat core sandwich panels.
