Tests and evaluation on personnel anti-shock tiles based on dummy shock response
Underwater explosion shock can produce extremely high acceleration, resulting in severe human injuries. Under the vertical shock acceleration from bottom to upward, the crew standing on decks receive extreme high shock load firstly, the calcaneus and ankle joints subject from heavy injury. The new developed anti-shock tiles can absorb shock energy and degrade shock load by its rubber material. In this paper, the new double-half sine wave shock machine is utilized to simulate 3 typical shock levels, and Hybrid III dummy is used as a carrier to substitute for the live man, and the shock response are recorded by sensors inside dummy. The test results show that the tiles could attenuate shock load by 60% at least, which proves the tiles can drop ship shock injury greatly.
