摘　　要：高速槽道双体滑行艇是一种具备贯穿中间的槽道和两个深V型片体的船型,槽道内部的气体层可以起到减阻作用,是一种水动力性能优良的船型。针对该船的船型参数和槽道几何参数对水动力性能的影响进行研究,并探索其优化方法,为未来双体滑行艇新船型的开发奠定基础。本文以某型槽道双体滑行艇为研究对象,研究船型参数和槽道参数对阻力和航态的影响,并基于Savitsky经验公式和遗传算法进行阻力优化,同时采用CFD方法进行优化效果验证,得到水动力性能更优越的槽道双体船型。High-Speed tunnel planning catamaran consists of 2 deep V-shape bodies and a tunnel through the whole hull,and its hydrodynamic is excellent.The tunnel’s internal gas layer can reduce resistance.The influence of hull and tunnel parameters on hydrodynamic is studied,and explore optimization method in order to lay the foundation of nesw planning catamaran form development.The article takes the tunnel planning catamaran as object to study the influence of hull and tunnel parameters on resistance and sea-keeping performance,and optimizes its resistance based on Savitsky empirical formula and genetic algorithm.At the same time,the CFD method was used to verify the results.
