水下爆炸空化效应作用下水面舰船的动态响应数值研究

Abstract

Shock trials are required for the lead ship of each new construction shock hardened ship class. Live fire shock trials are both complex and expensive. Finite element modeling and simulation provides a viable, cost effective alternative to live fire shock trials. This thesis investigates the effect of bulk and local cavitation on a threedimensional ship-like box model. The fluid surrounding the structure is modeled to capture the effect of cavitation. Viable results validate the modeling and simulation method used and provide the basis for further investigation into the use of fluid modeling in underwater explosion simulation.
