摘　　要：为研究入射波对船舶运动的非线性影响和非线性规律,针对不同波高不同频率的规则波作用下的空箱和装液浮箱的运动响应进行试验研究。研究结果表明:固定频率下不同入射波高引起的浮箱运动响应具有一定的非线性特征,入射波高越大,其非线性效果越强;低频入射波高越大,浮箱运动响应幅值与波高的比值越小;高频入射波高越大,浮箱运动响应幅值与波高的比值越大。In order to study the nonlinear effects and nonlinear laws of incident waves on ship motion,different wave amplitudes and different wave frequencies have been carried out in a wave flume and the responseamplitude-operator(RAO)results of steady-state roll motions have been analyzed.The study shows that RAO results of different wave amplitudes with fixed wave frequency are without consistency which indicates the incident wave has nonlinear influence on ship motion.The higher wave height of low frequency wave is,the smaller RAO results.The higher wave height of high frequency wave is,the bigger RAO results.
