With the spreading application of CAD/CAM, people place more and higher acquirements on geometric modeling. Toward to construct the complicated surfaces and generated high quality shape, people can't satisfy with the traditional NURBS based surface modeling method. Using partial differential equation method to generate surface is a new surface modeling method. This paper mainly discussion the application of partial differential equation analytical solution to the design of submarine surface, the result of analysis and simulation experiments show that PDE method can generated submarine surface commendably.%随着CAD技术应用的日益普及,人们对几何造型方法提出了越来越高的要求,对于复杂曲面的构造和高质量曲面的设计,传统的B样条方法已经不能满足人们的需求,用偏微分方程构造曲面,是一种新颖的曲面造型方法.本文主要讨论了偏微分方程的解析解在潜艇艇型设计中的应用.仿真实验表明,PDE方法能很好的构造出潜艇的艇型.
