- Abstract
Hovercraft should be designed to survive in the extreme loading conditions, such as an underwater explosion (UNDEX). This paper used a finite element model based Zubr-class like LCAC (Air-cushioned landing craft) subjected to UNDEX to study dynamic responses of hovercraft main hull structure subjected to underwater explosion. A procedure which links together the finite element method (FEM) and Acoustic-Structure Coupling (ASC) method is developed. First, finite element model tests are conducted to verify and validate the propagation of shock response generated by an underwater explosive experiment of Ramajeyathilagam [3]. Second, finite element simulations of the hovercraft model subjected to UNDEX simulation that detonates of 9kg of TNT were presented. The responses of main hull structure of the hovercraft model are also discussed. The numerical results show that besides global response, the main hull structure of hovercraft sustains severe local response especially is the main deck and skirt. The results could offer a valuable reference for hovercraft structure design.
