    Abstract
  • To directly observe and analyze the impulsion characteristics of the bubbles induced by underwater explosion, a light-emitting diode(LED) light source and its vibration isolator are designed. The characteristics of the vibration isolator under non-contact underwater explosion load are simulated. Finite element models of the LED, its vibration isolator, protection cover and water medium are built by using the software Hypermesh. Then the acoustic-structural coupling method in the software ABAQUS is employed to analyze the dynamic response of the isolator. By analyzing the time history curve of acceleration of two terminal points on the isolator, it is concluded that the medium density difference between inside and outside of the structure will affect transmission path of explosion shock wave, and the fixing mode of the structure will influence illumination of the LED light source. This research may provide reference for design of vibration isolator against underwater explosion for small structure.
