Abstract

Skirt is a part of air cushion vehicle (ACV) which plays a substantial role to create an over-pressure (above atmospheric pressure) between floor of structure and water surface. This pressure lifts main hull structure in order to travel through different surfaces as sea-surface, mud, and land. A suitable materials of ACV’s skirt is necessary to survive ACV before high-pressure bubble in under-water explosion (UNDEX). This paper builds up a technique which connects together the finite element method (FEM) and Coupled Eulerian- Langrangian (CEL) strategy to simulate and modify predicted data whereas the high-pressure bubble impact air cushion vehicle (ACV). To prove the promising results of this technique, authors conducted two feature studies from Klaseboer et al. (2005) [1] and A. M. Zhang again in Abaqus software [2], which showed the precision of the calculation model and method. With the similar above model, finite element simulation of the ACV’s skirt model subjected to high-pressure bubble impact that were presented, and discussed the skirt response of the hovercraft model. The consequences of numerical methodology could be as an important reference to outline ACV’s skirt structure.
