Abstract

Abstract: The dynamic design calculation method DDAM and time domain simulating method are introduced in this paper. Basic on the structure characteristic of the ship power package parts, the DDAM method and time domain load method are introduced respectively in frequency-domain and time –domain to analyze the shock resistance. The result indicates that the responses of different devices are relationship with the structure characteristic and the shock load direction. To the main turboset and the main reducing gear device, because of the connecting relationship between the parts, the dynamic response of the bolt, dowel and the connecting structure of them is more sensitively. The results can give certain reference to the analysis and calculation of the ship device shock resistance and the shock resistance design of the new ship device.

Key words
