为建立某内河船舶的操纵运动模型，以分离型模型为基础，建立基于数值计算的操纵运动模型框架，为获取操纵运动模型的水动力学导数，在数值环境下开展了静态斜拖试验(Static Oblique Towing Test， OTT)和动态圆周运动试验(Dynamic Circular Motion Test， CMT)，提出三次样条插值和最小二乘拟合的混合方法以提升非线性水动力导数的精度，缩尺船模Z形试验和回转试验验证了操纵运动模型的精度。结果表明，采用数值计算与混合方法所建立的操纵运动模型具有良好的精度，可用于内河船舶操纵运动建模。

To gain the maneuvering model of a typical unconventional ship, a numerical calculation based maneuvering model framework was established based on 3-dimensional mathematical modeling group mode model (MMG). To obtain the hydrodynamic derivatives in the maneuvering model, static oblique towing test (OTT) and dynamic circular motion test (CMT) were conducted in a numerical environment to obtain the forces on ship body. To improve the accuracy of nonlinear hydrodynamic derivatives, a hybrid method of cubic spline interpolation and least squares fitting was put forward. The zigzag and rotation tests of the scaled ship model verified the accuracy of the maneuvering model. The results show that the maneuvering motion model established by numerical calculation and hybrid methods has good accuracy and can be used for modeling unconventional ship maneuvering motion.
