摘要
Abstract
The ring-stiffened hull is one of the most common types of submarine pressure hull. Underwater shock response analysis is important for anti-shock design of submarine. The coupled acoustic–structural arithmetic was used to simulate and analyze the transient dynamic response of a submarine pressure hull with a ring-stiffened cylinder and two hemispherical ends, which experienced loading by an underwater explosion (UNDEX). The results showed that the distribution of local cavitations formed on the fluid–structure interface and the plastic strain at front position was smaller than at back position on the middle section. The numerical method presented in this paper can be used in designing stiffened optimum submersible vehicle.关键词
