    Abstract
  • To study the influence of the plexiglass-air interlayer structure on underwater explosion vibration, the foundation vibration signals for this structure caused by underwater explosion in the small pool (5.5 m in diameter and 3.62 m in height), the influence of different air interlayer thicknesses on the maximum vibration velocity was studied, HHT (Hilbert-Huang Transform) was used to analyze the vibration test signals by writing relevant programs based on Matlab software, studying the influence of different air interlayer thickness on the global frequency of vibration signals.Experimental results show that:under the condition of plexiglass-air interlayer structure, with the increase of air interlayer thickness, the maximum vibration velocity decreases first and then increases, and the vibration isolation effect is the best when the thickness is 120 mm.The amplitude corresponding to the global frequency can be obtained by means of HHT analysis, the amplitude attenuation of the 5-15 Hz low frequency section is obvious, the action time is shortened, which can effectively prevent the resonance phenomenon between the building and structure.The experimental results and analysis have certain theoretical reference value for underwater blasting engineering protection and structural design of lightning protection bunker for military ship.
