摘　　要：采用船体参数变形工具与CFD数值水池虚拟试验相结合的方法,分析某内河船首尾局部型线变化对船体阻力和自航性能的影响,获得船体阻力及收到功率随变形参数幅值的变化趋势,分析参数变形引起的兴波场和船表压力变化。The hull deformations were performed for an inland ship using a 3D parametrical hull modeling tool.With application of CFD method,the calm water resistance and self-propulsion performance were predicted at the specified design condition.The trends of ship resistance and delivered power changing with parametrical deformation were investigated,as well as the changing on the ship wave field and pressure field on hull surface.
