通过自行开发的测试装置并利用船模拖曳水池开展吊舱在不同舵角下水动力性能和动态载荷试验研究，为吊舱的整体结构和固有特性评估提供依据。试验测量吊舱在不同舵角下水动力性能，归纳和总结出吊舱整体推力、扭矩等参数随舵角变化的规律；并通过关键叶片动态载荷的测试，获得不同叶倍频时脉动力的幅值变化规律。通过试验测试方法获得的测试数据能有效地解析实际吊舱的操纵方式，验证吊舱推进设计的合理性，并为后续不同类型吊舱的开发提供了一种可行的性能预报方法。
In this paper, the dynamic performance and dynamic load tests of the azimuthal pod thruster at different rudder angles are carried out by using the self-developed test equipment and the towing tank of the ship model, which provides a basis for the evaluation of the overall structure and inherent characteristics of the azimuthal pod thruster. The launching hydrodynamic performance of the azimuthal pod thruster at different rudder angles is measured, and the rule of the overall thrust and torque of the azimuthal pod thruster change with the rudder angles is summarized. Through the test of the dynamic load of the key blade, the amplitude variation law of the pulse dynamic at different blade frequency doubling is obtained. Moreover, the test data obtained by the method can be effectively applied to analyze the control mode of the azimuthal pod thruster and verify the design effectiveness of the azimuthal pod thruster. It also provides a feasible performance prediction method for the subsequent development of different types of azimuthal pod thruster.
