摘要
系统阐述船舶波浪载荷预报的二维、二维半、三维方法以及水弹性力学分析方法,详细分析了完全弹性模型以及分段弹性模型的试验技术,并给出了船舶波浪载荷预报方法和模型试验研究现状和发展趋势。作为一个自然的发展趋势,船舶水动力学的发展方向是从频域转向时域、从切片理论转向完全三维理论、从线性转向非线性以及从势流转向粘流。船舶波浪载荷模型试验目前广泛采用只模拟一阶垂向振动频率的均质梁来开展试验。
In this paper,current prediction methods for wave-induced loads of vessels including 2D, 2.5D, 3D and hydroelastic analytical methods were reviewed systemically. Two different experimental methods so called fully flexible models and flexible segmented models were analyzed in detail. Finally, a brief perspective was given to show the status quo and development of prediction methods of wave-induced loads and .model test methods. As a natural trend,there are moves from the frequency domain to the time domain, from strip theory to fully 3 D schemes, from linear to nonlinear problems, and also from potential flow to viscous flow computations. Using a uniform beam to scale the first vertical mode is widely used to model test of wave-induced loads at the present time.
