本文通过实验和数值模拟研究了浅水晃荡情况下船舶受迫横摇运动的冲击压力。在低于第一晃动频率的频率下，发现冲击压力的最大值。实验结果进行了比较与使用光滑粒子流体动力学（SPH）获得的数值。讨论了粘性和密度重新初始化对SPH结果的影响。提出了一种用SPH法计算壁面压力的新方法。(C)2008爱思唯尔有限公司保留所有权利。
In this article, impact pressure in the case of shallow water sloshing is investigated experimentally and numerically for forced rolling motion. The maximum values of impact pressures have been found for a frequency lower than the first sloshing frequency. Experimental results are compared with numerical ones obtained using smoothed particle hydrodynamics (SPH). The influence of viscosity and of density re-initialization on the SPH results are discussed. A new method for calculating the pressure on walls with SPH is presented. (C) 2008 Elsevier Ltd.
