VIBRATION DAMPING CHARACTERISTIC TESTER

PURPOSE:To facilitate the testing of damping characteristic of a vibration damper, by submerging a connecting body of a vibration damper fitted with an accelerometer at both ends thereof and a mimic towing type wave receiver into an experimental water tank to apply a vibration thereto by a vibration application means. CONSTITUTION:When a vibration damper 2 to be towed together with a towing type wave receiver by a ship is tested, first, accelerometers 10 and 11 are mounted at both ends of the vibration damper 2 while a mimic towing type wave receiver 18 at the same mass as the towing type wave receiver actually to be used is connected at the other end thereof to be submerged into a water storage tank 8 filled with sea water or the like. A weight 20 is provided at the other end of the wave receiver 18 through a wire rope 19 to apply a tension equal to that which would be done when it is towed. A vibration applying means 14-17 and readings of both the accelerometers 10 and 11 are compared to determine camping characteristic. This provides a highly reliable data easily without actual towing.
