Abstract
PURPOSE:To reduce the braking water depth of a body to be tested, by arranging a wire body coupled with a net for tested body catching on a drum so that rotary driving and braking are possible. CONSTITUTION:When the body to be tested is fallen, it strikes on the surface of water strongly and while the minus acceleration and the maximum surface pressure, shock energy, etc., that the tip receives are recorded on an instrument, etc., it reaches the net 3 at large remaining speed. While the net 3 and wire cable 4 are aligned with each other, strong torque operates on the drum 5 of a friction brake 6. While the drum 5 is braked by the friction brake 6, the residual energy is absorbed by the friction brake speedily to stop the motion of the body 1 to be tested.
