摘　　要：针对某4 万吨散货船,分别计算了是否安装前置预旋导轮的船舶线性操纵运动水动力导数.并根据计算 得到的水动力导数预报了±35°回转运动和10°/10°、20°/20°Z形运动,分析了前置预旋导轮对船舶操纵性能的 影响,为导轮的优化设计提供了参考.A 40 thousand tons bulk carrier was taken as research object. Linear hydrodynamic derivatives of the carrier with or without pre-shrouded vanes （ PSV） were acquired through numerical simulation. Then performances of turning motion （35°）and zig-zag motion （ 10°/10°,20°/20°）were predicted by using Abkowitz model, and effect of PSV on ship maneuverability is analyzed. It can provide reference for optimal design of pre-shrouded vanes.
