| 摘 要： | 本文利用非线性振动理论研究了参数激励频率和波浪的强迫激励频率相同且等于艏摇固有频率2倍时的船舶1/2亚谐共振运动,揭示了船舶在低速航行、遭遇频率相对较高时,积累艏摇运动导致横甩发生的机理.

| Abstract: | Consider the situation when the frequency of parametric excitation and forced excitation is double of natural frequency of yaw motion,the 1/2 sub-harmonic resonance yaw motions of ships are studied using nonlinear vibration theory.Explored the mechanism of broaching due to cumulative yaw motion under low velocity and relative high encounter frequency. |

| Keywords: | broaching yaw nonlinear vibration parametric excitation forced excitation |
