Abstract
[Objectives] In order to improve the standards of the anti-shock assessment testing of shipboard equipment,[Methods] the shock response data of the low-frequency vibration of a 200-ton floating shock platform is analyzed. [Results] The difference between the horizontal and vertical low frequency response of the floating platform is not obvious,which indicates that the floating platform diversion device has a significant effect;at least in the low frequency range,it can effectively adjust the vertical and transverse shock strength ratio of the floating platform. There are inflection points in the low frequency band and high frequency band of the low frequency shock spectra of the floating platform;the low frequency inflection point appears at about 4 Hz while the high frequency inflection point appears at about 15 Hz.[Conclusions] The results show that the low frequency shock response of different parts of the floating platform is the same,which means that the low frequency shock response is mainly the rigid body movement of the whole floating platform.关键词
