Anti-shock threshold values of shipboard equipments based on ship hull and equipment integrated analysis

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.
