中文摘要：

提出了一种远场水下爆炸作用下舰船设备冲击响应一体化动力学模型。该模型将动态设计分析方法（DDAM）与Taylor平板理论相结合，使得对舰船设备冲击响应分析更为高效。将船体外壳看做平板，将船体各层甲板和设备看做附加在平板上的多个质量，将水下爆炸冲击波看做指数衰减波，形成了一维分析模型。能够根据水下爆炸当量、爆距、舰艇吨位、总尺度、结构和设备质量与支撑刚度等参数预测舰船与设备的冲击响应。预测结果与舰船缩比模型水下爆炸试验结果进行了对比。从总体上看，船体冲击响应谱的趋势和量级一致。

英文摘要：

An integrative dynamic model for the ship hull and the shipboard equipment dynamic response due to far field underwater explosion is developed. The model incorporates the Dynamic Design Analysis Method （DDAM） into the Taylor Plate Theory, and enables the shipboard equipment dynamic response analysis to be performed more efficiently. The model is formulated by assuming the ship hull to be a flat plate with an N-mass deck and shipboard equipment attached to the hull. A one-dimensional analysis is used to represent the explosion wave in water. The pressure wave is assumed to be a decaying exponential function. The model can predict the ship hull and the shipboard equipment shock response based on the underwater explosion charge weight, stand off distance, the Ship＇s Tonnage, principal dimensions, approximate ship hull structure and shipboard equipment mass and support stiffness parameters. The analytical results based on the model are compared to that of scaled ship model underwater explosion experiment results. In general, the spectrum values of the hull motion are similar in shape and magnitude to the experiment.
