摘　　要：为了能够灵活划分船体网格,减少船体水动力载荷计算时繁重的建模工作,同时降低对国外有限元建模软件的依赖,为多种边界元方法提供可靠的网格输出接口,基于B-spline曲线开发了一套适用于复杂船体的水动力网格划分方法,并通过对Wigley RT船型和20000 TEU集装箱船进行剖面和水动力网格划分来验证程序的准确性。结果表明,该方法能够准确、高效地表达具有方艉和球鼻艏的复杂船体外形,具有广阔应用前景。An auto-generating method of ship hull mesh based on B-spline is developed in order to generate the hull mesh flexibly and reduce the heavy modeling work on the hull mesh,as well as reducing the dependence on foreign finite element software and providing a reliable mesh for the boundary element method.The accuracy of the method is validated by generating mesh of WigleyRT ship and 20000 TEU container ship.The results show that the method can express the shape of the hull with transom stern and bulbous bow accurately and efficiently,which has broad application prospect.
