Abstract An active control method is proposed to suppress the lateral vibration transmission in a shaft-hull coupled system of underwater vehicles subject to the excitation of propeller forces. The active stern support, which uses a Stewart structure to replace the traditional surface support in the stern bearing, is employed to suppress vibration transmission from the shaft to the hull structure. The dynamic model of the shaft-hull system embedded with the active stern support is established. The characteristics of vibration transmission in the system and the feasibility of active control are analyzed and the attenuation of vibration induced by the lateral excitation of propeller forces is also calculated. An experimental system was built to verify the effectiveness of the control method. Numerical and experimental results have shown that the active stern support is able to suppress the lateral vibration transmission under the excitation of propeller forces, and the attenuation of the normal vibration of the hull structure can be achieved.
