• There is no peaking in the response but simply a smooth roll-off above the natural frequency.

    响应期间高峰期只是简单固有频率上平滑跌落

  • A nonlinear parametric excitation equation is obtained for ships in longitudinal waves, and the dynamic stability is analyzed when the natural frequency of heave and roll are approximately equal.

    本文建立了航行船舶非线性参数激励横摇运动方程,研究了当升沉固有频率接近横摇固有频率船舶稳定性

  • The roll is increased and severer than shipping state when the frequency of wave is similar as the natural rolling frequency of ships.

    船舶低航速状态下涌浪周期接近船舶自然横摇周期时,船舶摇摆航行时更为剧烈。
