| 摘 要： | 探讨了大风浪中顺浪航行的危险和产生这些危险的机理.从稳性降低的角度考虑,当船长与波长接近、波速与船速接近时顺浪航行危险最大;从尾淹和打横的角度考虑,当波长超过2倍船长、波速与船速接近时顺浪航行危险最大;从横摇的角度考虑,顺浪或者斜顺浪航行较顶浪或者斜顶浪航行更容易发生横谐摇.根据对危险的机理分析,并结合有关的理论研究成果和实际操船实践,提出了各种船舶顺浪和斜顺浪航行的操纵措施.

| Abstract: | Firstly,the dangerous situation in following and quartering seas and their mechanisms were investigated.From view of reduction of stability,when the ship's length and speed are nearly equal to the length of wave and wave velocity respectively,it is the most dangerous for a ship sailing in the following seas.From view of pooping and broaching-to,when the length of wave exceeds two times of ship's length and ship's speed is nearly equal to wave velocity,it is the most dangerous for a ship sailing in the following seas.From view of synchronous rolling,it is easier to have a synchronous rolling in following and quartering seas than in heading and bowing seas.Based on above investigation and combining with appropriate theoretical investigation result and ship handling practice,ship handling measures for various ships in following and quartering seas were proposed. |
