正交设计法在圆舭快艇初步设计阶段的应用

Application of Orthogonal Design to Preliminary Design in High speed Round Bilge Boat

简单分析了影响高速圆舭艇性能的主要尺度及系数，以内河某短途航线为例。

This paper briefly analyses some main dimensions and form coefficients influencing the function of high speed round bilge boats, and puts forword a method based on orthogonal design combining multipurpose optimization to determine main dimensions and form coefficients of high speed round bilge boat in preliminary design. The calculating results are presented for a short route on an inland river.
