针对舰船型线设计与流体动力性设计的独立导致型线形态与流体动力性能协同不足问题，为同时满足曲面光顺性、低阻力等需求，提出工业设计视角下舰船型线设计与流体动力性能协同设计方法。该方法以核心工程数据结构和几何数据组织方式为支撑；提出基于非均匀有理B样条（Non-Uniform Rational B-Splines，NURBS）曲面的舰船型线设计与流体动力性能协同设计方法，通过双参数控制构建舰船曲面骨架，并结合横向和纵向的局部调整完成舰船型线设计与流体动力性能的曲面生成，实现协同设计。测试结果显示，该方法具备局部细化控制能力，适用于船体曲率变化复杂的区域，确保曲线的连续性；设计曲面的浮心位置变化均控制在0.47%～0.63%。
To address the issue of insufficient coordination between ship profile design and fluid dynamic performance caused by the independence of ship profile design and fluid dynamic performance design, a collaborative design method for ship profile design and fluid dynamic performance from an industrial design perspective is proposed to simultaneously meet the requirements of surface smoothness and low resistance. This method is supported by core engineering data structures and geometric data organization methods; Propose a collaborative design method for ship profile design and fluid dynamic performance based on Non Uniform Rational B-Splines (NURBS) surfaces. The ship surface skeleton is constructed through dual parameter control, and the ship profile design and fluid dynamic performance surface generation are completed by combining local adjustments in the horizontal and vertical directions, achieving collaborative design. The test results show that this method has the ability of local refinement control and is suitable for areas with complex changes in ship curvature, ensuring the continuity of the curve; The variation of the floating center position of the designed surface is controlled between 0.47% and 0.63%.
