The theoretical basis and main methods of numerical simulation of thepressure distribution for sedan body surface are introduced in this paper.

本文介绍了轿车车身表面压强分布的数值模拟的理论依据及相应方法。

The main content included in the paper is as follows: The European identification methods of type of wave load is introduced and compared with the methods in Code of Hydrology for Sea Harbour. In order to reveal their difference, they are tested by the experiment data. The relation between phase and frequency are analysed through the Hilbert and wavelet transformations. And a new method of identifying the breaking wave load is set up based on the linear relation between wave height and wave press before the breakwaters. The probability distribution is tested by the statistic of experiment data. Based on the experiment data, the paper analysed the influence of reflection coefficient according to different factors, and its property is got. The work property of charmfered breakwater under breaking waves is analysed. Through the statisticof its wave press and wave force the distribution of press on the breakwater front face and its reducing effect to breaking wave force are proved.

本文基于此，通过实验研究，主要作了如下工作：介绍了欧洲波态划分方法，分析与我国方法的异同，通过实验进行了验证；通过 Hilbert 变换和小波变换对波浪破碎的相频特性进行了分析，通过建立波高与波压关系来判别破碎波浪力；对破波条件下波浪力的分布进行了统计研究，验证了其分布类型；利用实测资料，分析了不同因素对反射系数的影响，得出了不同周期、波浪要素、破碎率下反射系数体现的不同规律；分析了破碎波作用下削角堤的工作特性，通过对堤面所受的波压力和总力的统计分析，验证了压强分布规律及削角堤对波浪力的削减作用。
