滑行艇波浪中砰击压力极值研究

滑行艇在波浪中高速滑行时，会引起局部较大的砰击载荷和非常复杂的表面压力分布。为了在保证安全的前提下将装载能力和动力最大化，艇体初步设计时必须合理的估算使用海域可能出现的局部极限载荷大小，来调整艇体抗压能力，获取最优化设计。通过在规则和不规则波浪中的模型试验，测得艇体局部受到的砰击压力极值及特性。并引用简单有效的方法计算该值，与试验测量值吻合较好，证明该方法有一定的工程应用性。

Research on the extreme value of slamming force of planing craft in waves

Local slamming loads and very complicated pressure distribution will be found on the planing hull surface, when it is moving at high speed in waves. The load capacity and power need to be maximized under the premise of safety insurance. So the extreme value of slamming loads in the sea area should be taken into consideration at the stage of preliminary design, for the purpose of getting the optimized design. Model test is carried out in regular and irregular wave. The extreme value of slamming loads is measured, and the characters are analyzed. A simple and effective method is present for the calculation of extreme load. The results are validated by the measurements. It is shown that can be extended in engineering application.
