DEVICE FOR MEASURING ADDED RESISTANCE IN WAVES

摘要

The purpose of the present invention is to provide a device which can, with respect to performance evaluation of a ship in waves by means of a model test, reduce the component of primary wave power in the total resistance in waves and measure the total resistance in waves by means of a dynamometer that has appropriate capacity, and thus can consequently have improved measurement accuracy of additional resistance in waves. In order to attain the purpose, the present invention provides a device for measuring added resistance in waves, the device comprising: a moving unit which is disposed on a towing carriage, is connected to a model ship by means of a connecting rod, and moves forward and backward according to the forward and backward oscillation of the model ship; a restraining unit which is provided on the moving unit and partially restrains the movement of the moving unit; and a dynamometer which is provided on the connecting rod and measures the total resistance in waves applied to the model ship.
