舰船动力设备抗冲击评估方法综述

舰船动力设备的抗冲击能力是舰船安全稳定运行的重要保障,而合理的评估方法可以较为方便地获得动力设备的抗冲击特性预测结果。首先,将冲击过程分为低/高速碰撞冲击过程和非接触爆炸冲击过程,基于主从系统关系,阐述舰船设备非一体化与一体化抗冲击方法,总结舰船动力设备的抗冲击研究进展,提出舰船动力设备抗冲击领域的重点研究技术。然后,结合舰船设备一体化方法(分为等效静力法、动态设计分析法及时域分析法)的特点,总结得出:等效静力法仅适用于低频影响的结构简单动力设备;动态设计分析法忽略了邻近设备、隔振系统及船体结构对冲击输入载荷的影响;时域分析法仅适用于爆炸冲击等特定场景或冲击信号输入;而舰船设备一体化考虑了船体结构–基座–隔振系统–动力设备形成的多自由度系统,其计算结果更贴近于实船工况,但建模和计算成本较高。最后,展望了舰船动力设备抗冲击的重要发展方向,包括评估方法的准确选取、抗冲击试验台的合理改进、冲击响应信号提取分析、动力设备多场耦合作用分析、动力设备物理模型简化研究、内部流动介质等效替代研究、数据挖掘和深度学习方法融合等。
