摘　　要：船舶作为水上交通工具,常常需要在风浪下航行,虽然横摇并不会受到波浪力的干扰,但在波浪与船体相对位置出现变化时,水线面积会随之发生波动,由此引起了稳定性的变化。在这一前提下,即便初始的横向扰动比较小,也可能引起较大幅度的横摇运动。当参数横摇现象出现后,会对船舶的航行稳定性造成不利影响,及时有效预报迎浪参数,能够为船舶减摇提供依据。在船舶迎浪参数预报及减摇研究中,可以应用函数响应法,依托该方法对相关参数进行计算,确保结果准确、可靠。As a water vehicle,a ship often needs to navigate under wind and waves.Although rolling will not be disturbed by wave forces,when the relative position of the wave and the hull changes,the waterline area will fluctuate accordingly.Under this premise,even if the initial lateral disturbance is relatively small,it may cause a relatively large rolling motion.When the parametric roll phenomenon occurs,it will adversely affect the navigation stability of the ship,and timely and effective prediction of the head-on wave parameters can provide a basis for ship anti-rolling.In the ship heading wave parameter forecasting and anti-rolling research,the function response method can be applied,and the relevant parameters can be calculated by relying on this method to ensure the accuracy and reliability of the results.
