STUDY OF FALLING SHOCK ON THE WATER SURFACE BY HUMAN MODEL

At the critical moment of distress, abandoning ship is done individually or collectively. The studies were performed to obtain shock deceleration and its duration time in the case of individual escape. The experiments were made by a human model using life-saving appliance at the drop testing tank of Ship Research Institute. The results are summarized as follows: (1) The fall-time can be obtained using free fall calculations for heights under 8 meters, in case of greater heights it is necessary to consider the air resistance. (2) The posture of falling body is scarcely changed through the fall. (3) The deceleration of slant fall is 10 times that of head-first or feet-first fall. (4) The shock duration time in case of head-first or feet-first fall is 100-300 milliseconds, and that of slant fall is 15-40 milliseconds. (5) Further study is expected for the determination of safety fall height limit, because it is necessary that medical research for human tolerances be established.
