摘要
基于非线性有限元软件ANSYS/LS-DYNA,建立了大体积复杂结构的典型舱室模型,采用流固耦合算法,仿真分析舱内爆炸载荷传播特性,得出舱室撕裂破口主要集中在舱壁角隅处,加强筋结构大变形破坏,舱壁结构解体飞散,舱内由于冲击波反射作用形成准静态压力区等结果,可为舰艇毁伤和防护提供参考。
A large complex cabin model was built based on ANSYS/LS-DYNA. Fluid-structure cou- pling method was used to simulate the dynamic response of ship cabin structure to blast loading. The con- clusion showed that the breaks were mainly concentrated on the corner of cabin, the failure mode of stiff- ened plate was given, and the cabin structure was disintegrated. The quasi-static pressure zone in the cabin were formatted by the reflection of shock wave. It could provide a reference for naval vessels damage and protection.
