摘要
深V型滑行艇模型纵向运动试验研究表明 :规则波中 ,升沉响应的平均值与静水航行时的重心升高极为接近 ,纵摇响应的平均值与静水航行时的纵倾较为接近 ,证实了相同航速下滑行艇在波浪中航行的纵向运动是相对于静水浮态的升沉纵摇运动 ;随着航速的增加 ,升沉响应峰值、纵摇响应峰值、垂向运动加速度峰值都向长波方向移动 ;速度较高、波幅较大时 ,升沉、纵摇。
Some experimental study on longitudinal motion of a model of a deep-V-shaped planning craft is carried out,its results show that the average value of heave in regular wave is very close to the value of vertical rise of gravity centre in still water,and the average pitching amplitude in regular wave is rather near to the value of trim in still water. Such results prove that the longitudinal motion of a planning craft navigating in waves is its combined pitching and heave motion when it navigates at the same speed in still water.As the model's speed is increased,the crest amplitude of heave,pitching and vertical motion acceleration move toward in the direction of the longer wavelength;when model is at high speed and the wave height is larger,the heave,pitching and vertical motion acceleration are all nonlinear.
