摘要: 为了确定设备抗冲击阈值，基于主从系统耦合振动理论，以船用增压锅炉、齿轮箱为研究对象，将船体与设备的一体化抗冲击数值实验的数值统计特征进行分析。通过大量算例结果分析，提出将冲击作用下设备应力响应标准差作为设备失效判据，并给出了设备冲击作用下应力响应标准差最大值计算经验公式。

Abstract: Based on the theory for coupled vibrations of master-slave systems, by choosing shipboard supercharged boilers and gear cases as research objects, the numerical statistical characteristics of numerical experiments for ship hull and equipment integrated analysis were discussed to determine the anti-shock threshold values of shipboard equipments. The standard deviations of stress values for equipments subjected to shock load were put forward as the failure criteria of shipboard equipments through large numbers of exemplification analysis. And an empirical formula of the maximum value of standard deviation was given.
