摘要

水陆两栖飞机的着水载荷是影响结构设计的主要因素之一。本文应用数值仿真与模型试验相结合的方法对船体着水载荷进行了研究。数值仿真建立了包含空气场的有限元模型，计算了不同船底截面形式、结构重量、入水速度下的楔形体局部砰击压力变化及分布，并同模型试验结果进行了对比。结果表明，数值结果与模型试验值吻合良好，并得到了两种截面形式的压力分布规律，可为水陆两栖飞机船体构型的设计提供参考。

Abstract

The water load of amphibious aircraft is one of the main factors influencing the structure design. The water load of the hull were studied by numerical simulation and model experimental approach. The finite element model contains the air field. The local pressure variation and distribution were calculated with different sections of the bottom, structural weight and the speeds of entry water, and results were compared with tests. The results show that the numerical results are in good agreement with the model experimental value. Pressure distribution of two sections were obtained. It can provide reference for amphibious aircraft hull configuration design.
