Problems solved by technology

Passive vibration control technology can be easily implemented due to its simple design and low manufacturing cost, but it has certain limitations when it comes to achieving a precise level of vibration control
That is, when the frequency band that needs to be removed is wide, it is difficult to effectively deal with it only by passive vibration control technology

Abstract

The invention relates to a method for measuring resistance of a model ship using active vibration control technologies. Via the method, the mechanical vibration factor (ie, external vibration) transmitted from the measurement frame of the towing vehicle used in the model ship test is measured, vibration that is out of phase with the measured vibration factor (ie, anti-vibration) is generated and applied to a measurement frame of a towing vehicle, and precision measurement of resistance to model ships is performed after mechanical vibration is minimized.

Description

technical field [0001] The present invention relates to a kind of method for measuring the resistance of a model ship utilizing active vibration control technology, and in particular to a method for measuring the mechanical vibration factors (i.e. ) is measured, followed by generating vibrations in opposite phase to the measured vibration factor (i.e., anti-vibration) and applied to the measurement frame of the towing vehicle, thereby reducing the resistance experienced by the model ship after minimizing the mechanical vibration A resistance measurement method for model ships using active vibration control technology for precise measurements. Background technique [0002] Usually, in order to verify the ship design, a model ship is produced in which the designed ship is scaled down to a certain scale, and then it is combined with a towing vehicle of a ship type test tank to perform a model test. At this time, various model tests are performed according to the purpose, and v...
