摘要

摘要: 采用三维势流理论及多体动力学理论建立了波浪中近距离并行航行多船波浪作用力及运动响应的计算模型.为考虑航速效应对船体间自由面的影响，采用三维移动脉动源Green（格林）函数来模拟船间的辐射波及绕射波.采用该数学模型求解了零航速及有航速情形下两船近距离并行时的流体动力项及运动响应，和模型试验结果比较验证了方法的可靠性.将该方法推广至三船并行航行的情形，重点分析了三船并行时水动力干扰和两船并行时水动力干扰的差异.

Abstract: A three-dimensional frequency-domain calculation model based on the potential flow theory and multi-body dynamics theory was developed to investigate wave loads and free motions of multiple closely-spaced, hydrodynamically interacting ships advancing parallel in waves. In order to consider the speed effects on free surface in the gaps between these ship bodies, the translating-pulsating source Green’s function was chosen to simulate the radiation and diffraction waves. The model was validated through solving of the hydrodynamic terms and free motions of two parallel closely-arranged ship models advancing at zero or positive forward speeds in regular waves. Numerical results were also presented in the case of three parallel ships. Comparison of the dynamic behaviors between the two-ship case and three-ship case shows that in the two cases hydrodynamic interaction effects are quite different. The presented model is useful to predict wave loads and free motions of multiple vessels in underway replenishment on the sea.
