摘　　要：为了更加合理地评估操雷浮囊装置在海面漂浮过程中的生存能力,文中依据有限元方法并基于商业软件Fluent建立三维数值水槽。采用边界造波法及源项消波法来实现水槽的造波和消波功能,对操雷浮囊装置施放海域的波浪情况进行模拟。在此基础之上,建立波浪与操雷浮囊结构相互作用的流固耦合模型,分析了三级海况下海浪对操雷浮囊结构生存能力的影响。仿真结果表明,建立的三维数值水槽产生的波浪具有良好的稳定性及可重复性,可得到浮囊最大应力响应的位置及数值,为操雷浮囊装置的设计与改良提供了重要的数值参考依据。In order to more reasonably evaluate the survivability of the floating bag device of a special torpedo, a three-dimensional numerical flume was established based on the finite element method and the commercial software Fluent. The boundary wave method and the source item method were used to realize the wave-making and wave-eliminating functions of the water tank, and the wave conditions of the sea area in the operation of the lightning-floating device were simulated. On this basis, the fluid-solid coupling model of the interaction between wave and thunder floc structure was established to analyze the influence of ocean waves on the survivability of the thunder floc structure. The simulation results showed that the wave generated by the three-dimensional numerical flume had good stability and repeatability, and the position and value of the maximum stress response of the floating bag were obtained, which provided an important numerical reference for the design and improvement of the experimental torpedo with floating bag device.
