摘　　要：为了在研制阶段评估某大型水陆两栖飞机的抗浪性,开展了缩比模型水池试验方法研究,定量分析了水池试验模型与实机之间气动升力/阻力系数的差异,研制了恒力装置,利用该装置可将试验模型气动升力系数补偿到与实机一致的水平。在此基础上开展了缩比模型在不同波高、波长及速度条件下的水池拖曳试验,得到了试验模型俯仰角、升沉响应特性,研究了谱分析法和线性缩比法对实机抗浪性预报的适用范围和优缺点。结果表明:谱分析法在速度小于90 km/h时预报结果较为合理,中高速的预报结果与实机运动现象有明显差异;线性缩比法适用速度范围涵盖从低速到离水起飞,但仅能用于定性分析波长、速度对运动响应的影响,定量分析的准确性还有待验证。In order to investigate the seakeeping performance of amphibian,the scaled model tank test method is studied.The difference of aerodynamic lift and drag between the model and amphibian is analyzed quantitatively,and a kind of constant force mechanism used to compensate air lift to the model is developed,it can modify the aerodynamic lift of model to the same as that of the aircarft.Combined with the model test,the application range,davantages and disadvantages of spectral analysis and linear reduction method used to forecast amphibian performance is analyzed.The results show that spectral analysis is an effective way only when speed lies below 90 km/h,the forecasted result at higher speed differences from the actual situation.Linear reduction method could be used at a whole range speed and could be used to analyze the influence of wave length and speed on motion response qualitatively,but the quantitative analysis needs further examining.
