摘要

摘要: 为研究射流冲击载荷对结构的作用效果，从理论和数值角度研究了射流的载荷特性，以舱段模型实验为研究对象，建立了射流计算模型，结合实验数据，对射流冲击问题进行了分析。结果表明，射流冲击能够造成结构强烈的局部响应，某些情况下，射流冲击载荷引起的结构响应甚至比冲击波载荷引起的响应更大。因此，中近场水下爆炸实验需要考虑射流的影响。建立的射流模型能够较好地反映射流冲击的载荷特性，为水下爆炸实验分析提供了一种新的手段。

Abstract: In order to study the damage effect of ship structure subjected to jet impacting, characteristic of jet loading was investigated theoretically and numerically. A jet impact-model was verified based on a ship cabin model underwater explosion test. An analysis was made by combining the calculation results and test data. Results show that the jet impact can induce a strong local response on the structure. Under certain circumstance, jet impacting response is more severe than that caused by shock wave even when bubble incepts at a relatively far position. Therefore, jet impact problem cannot be considered only in proximal underwater explosion test. The jet impact-model developed in this work could reflect the loading feature accurately, and would provide reference to underwater explosion experimental analysis.
