| 摘 要： | 目的 为了提高航海模拟器中小水线面双体船（SWATH）的模拟精度，更好地掌握此类船舶的操纵特性， 方法 根据SWATH船型的运动特点，在MMG三自由度模型的基础上，较为完整地计入耦合的纵荡、横荡、艏摇、横摇及纵摇运动，建立SWATH的五自由度运动数学模型。基于此应用模型建立SWATH的实船数学模型，对该数学模型进行微分求解，仿真模拟SWATH的旋回运动、Z形运动，并进行定性分析。 结果 分析显示：仿真模拟结果符合SWATH操纵运动原理及实际运动特征，验证了数学模型的准确性。 结论 该模型可真实反映实船的运动规律，可应用于航海模拟器中。

| Abstract: | To develop marine simulators of Small Waterplane Area Twin Hull (SWATH) ships and gain a better understanding of the maneuverability of the SWATH, a mathematical model with five Degree of Freedom (DOF) for SWATH has been established, in which the surge, sway, yaw, roll and pitch motions are all considered. The characteristics of the SWATH ship form and the hydrodynamic interaction among the twin bodies, twin propellers and twin rudders are taken into consideration on the basis of the three DOF maneuvering mathematical model. To verify the effectiveness of the modeling and ensure the use of the model in marine handling simulators, a detailed model is tentatively established on the basis of empirical formulas. Based on the acquired results, tests were performed to simulate the steady turning and zigzag motions of the ship. The results are in accordance with regular pattern and trend of motion of SWATH ships. This verifies the effectiveness of the mathematical model of the turning movement. |
