Abstract

Free running model tests and a system-based method are employed to evaluate maneuvering performance for a Small Waterplane Area Twin Hull (SWATH) ship in this paper. A 3 degrees of freedom Maneuvering Modeling Group (MMG) model is implemented to numerically simulate the maneuvering motions in calm water. Virtual captive model tests are performed by using a Reynolds-averaged Navier-Stokes (RANS) method to acquire hydrodynamic derivatives, after a convergence study to check the numerical accuracy. The turning and zigzag maneuvers are simulated by solving the maneuvering motion model and the predicted results agree well with the experimental data. Moreover, free running model tests are carried out for three lateral separations and the influence of the lateral separations on maneuvering performance is investigated. The research results of this paper will be helpful for the maneuvering prediction of the small waterplane area twin hull ship.

小水线面面积双船体操纵性能试验与数值研究

采用自由运行模型试验和基于系统的方法对小水线面双体船(SWATH)的机动性能进行了评价。采用三自由度机动建模组(MMG)模型对静水中的机动运动进行了数值模拟。采用reynolds -average Navier-Stokes (RANS)方法进行了虚拟圈养模型试验，获得了流体动力导数，并进行了收敛性研究，验证了数值精度。通过求解机动运动模型，对转弯和之字形机动进行了仿真，预测结果与实验数据吻合较好。在此基础上，进行了三种侧向分离的自由运行模型试验，研究了侧向分离对机动性能的影响。本文的研究结果将有助于小水线面面积双体船的机动预测。
