摘　　要：高速艇多采用滑行艇型,在波浪中高速航行时,其砰击载荷、运动和结构响应具有十分复杂的强非线性特征。目前尚无有效的数值方法评估高速艇的砰击载荷及其响应,因此多采用模型试验的方法进行测试。本文针对某高速滑行艇开展水池模型试验研究高速艇在波浪工况下的砰击载荷和响应特性;根据相似理论和水池参数确定模型主尺度和波浪工况;根据测试目的制定模型的结构方案,确定模型的参数测点布置方案,并制定高速艇模型试验方案;试验获得高速艇模型在波浪工况下高速航行时的系列砰击压力、加速度和船舯弯矩等试验数据,并对相关数据进行统计分析;通过研究航速、波高、波长等参数对高速艇砰击载荷和响应的影响,得到各工况下压力峰值沿船长的变化规律以及高速艇在波浪海况下的砰击载荷和结构响应特性。本试验研究对于高速艇的实船设计研发具有指导意义。High-speed crafts are mostly planing boats.When a high-speed craft is sailing at a high speed in waves,the slamming loads,motion and responses have very complex strong nonlinear characteristics.At present,except the model test method,there is no effective numerical method to evaluate the slamming load and response of a high-speed craft.In this paper,the model test of a high-speed craft was carried out to study the slamming load and response characteristics of the high-speed boat in waves.The main scales and wave conditions of the model were determined according to the similarity theory and the parameters of the tank,the structure scheme of the model according to the test purpose while the layout of the parameter measurement points of the model and the final test scheme of the high-speed craft model were finalized.Through experiments a series of test data such as slamming pressure,acceleration and midship bending moment of the high speed craft model sailing at high speed under wave conditions were obtained,followed by statistical analysis of the relevant data.By studying the influence of the parameters of speed,wave height and wave length on the slamming load and structural response of the high-speed craft,the variation law of pressure peak along the ship length and the slamming load and response characteristics of the high-speed craft under wave conditions were obtained.The study is of great significance in guiding the design and development of high-speed crafts.
