摘　　要：采用计算机数值模拟方法,在FLUENT软件计算平台上建立了二维规则波数值波浪水槽,对透空平板、有梁面板结构底面受到的波浪冲击压强分布情况进行研究。数学模型采用RANS方程和k-ε湍流模型,以VOF方法处理自由表面。通过对不同工况的数值模拟和试验结果比较,验证了模型的造消波性能和应用的有效性。然后通过计算,得到了波浪冲击过程中面板底部冲击压强的分布规律,并对数据进行了分析和统计,提出了面板底面冲击压强分布宽度的拟合公式,作为工程设计的参考。To study the specialties of wave slamming on horizontal plate structures and beam-plate structures, we establish two-dimensional regular wave numerical models based on software FLUENT. Adopting RANS equations and standard k-~ equations and using the VOF method, we reconstruct the free surface. Through typical cases of wave slamming on panel structures are reproduced, and the models are verified by experimental data. Then with plentiful simulation the impact pressure distribution rules during slamming are obtained. The statistical distribution data are analyzed and the fitting formula of distribution width is put forward, which may serve as reference for the engineering design.
