| 摘 要： | 采用三维势流理论计算高架索航行补给中两船在波浪中的运动响应,将船体周围流场速度势分解为波浪入射势、自身绕射势、相邻船体的存在产生的绕射势、自身辐射势和相邻船体运动产生的辐射势,通过源汇分布法进行求解;对高架索索道上的恒定张力在耦合方程中表示为高架索瞬时张力系数矩阵;求解两船体在规则渡中的联立运动方程可得两船的运动响应.通过计算结果与高架索航行补给中两船运动响应的试验结果进行比较,吻合良好,说明文中的计算方法是可行的,在此基础上,对不同高架索恒定张力和不同浪向角条件下的接受船运动幅值响应进行计算并讨论.最后得出结论.

| Abstract: | The methods for calculating behaviour of two ships in replenishment of highine system in waves based on the 3-D potential-flow theory are introduced.The velocity potential over the ship hull is divided into the potential of the incident wave,the diffraction potential on ship A due to existence of ship A and ship B and the radiation potential on ship A due to the oscillation of ship A and ship B which are solved by the source distribution technique.The constant strain in highline is expressed by transient st... |
