摘　　要：流线型体具有很好的水下静动力特性,广泛应用于水下装备设计当中.为了探求流线型体结构的设计方法,在几种常用流线型体轮廓方程基础上,对比分析不同结构参数下二维流线型体的水下阻力特性,得出半椭圆+圆弧流线型的阻力特性最好.将这种流线型应用于工程实例,在空间约束范围内,设计出水下航行体的三维导流罩结构,采用仿真分析验证了结构设计的合理性,并测算出结构的水流阻力值.研究结果可为其它流线型体结构的设计提供参考.Streamlined body is applied to underwater equipment design widely since it has good static and dynamic characteristic.In order to seek the design method of streamlined body,based on several outline equations of streamlined body in common used,the drag characteristic of underwater two-dimensional streamlined body is compared and analyzed with different structure parameters.It is shown that the semi-ellipse with arc streamlined body has the best drag characteristic.Applied this streamline to engineering project,the three-dimensional dome structure is designed in spatial constraint for underwater vehicle.The dome structure is proved to be reasonable and its flow resistance is calculated accurately by simulation analysis.The research result provides a reference for other streamlined body design.
