摘要
Abstract
With the development of anti-shock research of equipment on navy ships, accurate prediction of the impact environment of the underwater cylindrical shells is of great significance for equipment distribution and installation. Underwater explosion experimental research on cylindrical shell is a high reliability measure, but it is very costly. While the cabin test is relatively simple and convenient. In this paper, the impact environments of the cabin and whole underwater cylindrical shell are compared mutually. It is found that the difference mainly exists in the low frequency range. The low frequency response of the underwater cylindrical shell is dominated by low order vibration modes, while the low frequency response of the cabin is mainly rigid body motion. According to the difference, a combination method of ship hull girder whipping motion theory with empirical mode decomposition method is put forward to forecast the impact environment of whole cylindrical shell. Results show that this method has a high simulation precision.关键词
