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. 本发明涉及一种能够对通过在模型船舶试验中使用的拖引车的测量框架传递过来的机械振动因素(即，外部激振)进行测量，接下来生成与所测量到的振动因素反相位的振动(即，防振)并施加到拖引车的测量框架，从而在将机械振动最小化之后对模型船舶所受到的阻力进行精密测量的利用主动型振动控制技术的模型船舶阻力测量系统。
