摘要
为克服海浪的随机性,应用波能谱理论,建立能够体现海浪不规律性运动的数学模型.根据建立的模型在合理的仿真条件下,运用Matlab软件进行仿真,并将仿真结果与国内外广泛采用的I.T.T.C单参数谱进行比较.由50条简谐波组成的海浪模型仿真结果与I.T.T.C单参数谱比较非常接近.实践证明该方法可以快速有效地模拟的海浪运动状态.
In order to overcome the randomness of the ocean wave,the actual motion state of the wave was simulated on computer. Appling the wave energy spectrum theory, the authors established the mathematical model, embodied the stochastic movement of the ocean wave. This model was simulated by Matlab under the reasonable conditions. The simulation results and the I. T. T. C single parameter spectrum which has been applied in engineering practices were compared and analyzed. The wave spectrum model composing of 50 simple harmonic wave reflected the actual motion state of the wave. Experiments prove that the method is efficient and effective in wave simulation.
