摘　　要：基于纵向函数的数学方法,研究并总结归纳出各纵向函数沿船体纵向方向上的变化趋势,设计出符合各部分线型特性的线型表达式,提出基于纵向函数的船体线型全参数化设计方法。凭借CATIA V5软件的曲面设计功能,运用VB.net程序设计语言对其进行二次开发,实现船体型线、曲面的全参数化自动设计。多组算例结果比较,分析形状控制参数对船体线型变化的影响,验证了该设计方法的可行性与灵活性。Based on longitudinal function in the design method of mathematical hull, the variation tendency of longitudinalfunctions along the longitudinal direction was researched and summarized. A parameterized design method of hull lines was presented based on the longitudinal function. By using the surface design function in CATIA V5, the automation design of hull lines and surfaces was achieved. A secondary development was applied to CATIA V5 by using VB. Net programming language. An analysis of the impact of the shape control parameters on the variation of hull lines was made with the comparison of groups of calculation to validate the feasibility and flexibility of the design method.
