摘　　要：根据操纵性运动线性方程与一阶KT响应方程对某三体船型操纵性运动进行预报。方程中的船体加速度类水动力导数采用Hess-Smith法计算,船体速度类水动力导数采用细长体理论并结合经验公式和图谱进行计算,舵导数采用短翼理论并结合经验公式和图谱进行计算。最后,根据理论计算结果对侧体位于不同纵向位置的三体船和单体船的操纵性规律、特性以及特征参数进行了分析、对比。计算结果表明,该计算方法具有良好的应用前景。The maneuverability movements of the trimaran were predicted based on the maneuverability linear motion equation and the first order KT response equation. The ship hull hydrodynamic derivatives were determined hy Hess-Smith method and slender hull theory. The rudder derivatives were determined by the short span hydrofoil theory with the empirical formula and chart; Finally the con- trast of the maneuverability regulation, feature and characteristic parameters between the trimarans and the mono-hull ships were done based on the theory calculation results. The analysis results show that present calculation results and methods both have good application prospects.
