Abstract

Abstract

The shock environment of floating shock platform for the equipment and the response of ship board equipment under different shock environment were studied by numerical simulation and theoretical analysis. Based on the calculation model of American intermediate floating shock platform, the shock environment of equipment base was compared with German BV specification. In order to analyze the difference of spectrum acceleration between the two systems in impact requirements of the equipment, numerical simulations for different ship board equipment were carried out. Through the modal method of virtual constraint boundary, a model for the multi-degree freedom system with basic excitation under different shock environment was proposed. Numerical analysis and theoretical results show that the spectrum acceleration of shock spectrum has little effect on the response of ship board equipment, but spectrum displacement and velocity have significant effect on equipment response. The response of multi-degree freedom system analyzed by theoretical calculations is consistent with the numerical simulation results. Meanwhile, during the design of floating shock platform, the influence of spectrum acceleration on equipment response does not need to be considered.
