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 model ship resistance measurement system using active vibration control technology, in particular to a mechanical vibration factor (that is, externally excited vibration) transmitted through the measurement frame of a towed vehicle used in a model ship test. ) To perform measurement, and then generate vibration (ie, anti-vibration) in the opposite phase to the measured vibration factor and apply it to the measurement frame of the towing vehicle, thereby minimizing the resistance to the model ship after the mechanical vibration is minimized A model ship resistance measurement system using active vibration control technology for precise measurement. Background technique [0002] Usually, in order to verify the design of a ship, a model ship is made that is scaled down to a certain scale, and then combined with the towing vehicle of the ship-shaped test tank to perform a model test. At this time, various model tests will be ...
