针对船舶设备在水下爆炸冲击环境下,其动态响应情况直接影响设备的工作性能和可靠性的问题. 从系统耦合振动理论出发,基于设备与船体一体化抗冲击分析方法,采用数值模拟方法对水下爆炸条件下的船舶大型设备及船体结构进行冲击响应时域分析. 研究结果表明,采用一体化分析方法的结果与实际试验吻合较好,同时通过确定合理的舱段长度,既可以减少计算规模,又能得到好的计算精度.

In the circumstance of underwater explosion, ship equipment's dynamic response characteristics are key factor affecting the working capability and reliability. Numerical simulation is done for the research of time domain dynamic structural response of large-scale ship equipments and ship structure on the condition of underwater explosion. The conclusion indicates that integrate analysis result coincides with that from experiments. Meanwhile, integrate analysis is used to determine the characteristic ship cabin structure element length, not only to reduce the amount of calculation but also for good precision.
