摘要
在船舶初步设计阶段,探求一种快速高效率的方法来确定优良船型.船型参数法通过高水平的描述符(形状参数)生成船体曲线和曲面所想要的几何外形.程序实现几何建模系统以船体的形状参数作为输入,以水动力计算所需要的船体型值作为输出,使几何船体与水动力性能成为一种内在决定性关系.因此,船型参数法是船舶水动力性能优化的重要基础和不可缺少的组成部分.
During the preliminary design stage, designers search after a fast and efficient method to determine the good form hull. The method of parametric hull design could generate curves and surfaces of the ship hull which shall be developed from high-level descriptors（form parameters） for their intended shapes. Building a geometric modeling system by program ,the input to the modeling process is a set of parameters while the output to the calculation of hydrodynamic performance is a set of offsets. Then, the form hull has a indirect effect on hydrodynamic performance inherently. The method of parametric hull design is not only a important foundation of hydrodynamic performance optimization, but also a indispensable component.
