三体船模型的阻力试验和数值预报

Model tests and numerical prediction on resistance of trimaran

在三体船兴波阻力数值计算的基础上,进行了三类试验。一是在给定片体纵向和横向间距条件下测试了不同船速的剩余阻力,二是在给定船速和片体横向间距条件下测试了不同纵向间距的剩余阻力,三是在给定船速和片体纵向间距条件下测试了不同横向间距的剩余阻力。试验结果显示,片体间的纵向和横向间距能在很大程度上改变三体船的剩余阻力,说明采用Noblesse新细长体理预报三体船的阻力和优化三体船的片体布局是可行的。

Three kinds of model tests were done based on the numerical calculation of wave resistance of a trimaran.Firstly,the residual resistance to the speed of a trimaran with a given longitudinal and transverse distance between the hulls was tested.Secondly,the residual resistance to the longitudinal distance between hulls of the trimaran with a given transverse distance at a given speed was tested.Thirdly,the residual resistance to the transverse distance between hulls of the trimaran with a given longitudinal distance at a given speed was tested.The results of the model tests show that the longitudinal and transverse distances have great influence on the resistance of the trimaran and that the resistance can be calculated and the configuration of the trimaran can be optimized using Noblesse′s slender ship theory.
