The invention relates to the technical field of navigation equipment, and provides navigation equipment, a ship shafting and a control method for transverse vibration of the ship shafting, the ship shafting comprises a propulsion shaft assembly and a tail shaft assembly, the propulsion shaft assembly comprises a thrust shaft, and the thrust shaft extends to the tail shaft assembly; the stern shaft assembly comprises a stern tube and an outer barrel, and the stern tube is arranged on the outer side surface of the thrust shaft in a sleeving mode; the outer cylinder sleeves the outer side surface of the stern tube; a friction damping energy dissipation structure is arranged between the outer cylinder and the stern tube, the friction damping energy dissipation structure comprises a friction damping sleeve and friction damping lantern rings, a pre-tightening part is arranged on the friction damping sleeve, the friction damping lantern rings are arranged on the pre-tightening part in a sleeving mode at intervals, and stacked piezoelectric ceramics are further arranged on the friction damping lantern rings in an array mode. When the ship shafting is subjected to transverse vibration, the stacked piezoelectric ceramics apply pre-tightening force, so that the outer surface of the stern tube and the inner surface of the friction damping sleeve rub each other, energy loss is generated, and transverse vibration of the ship shafting is restrained.

    本发明涉及航海设备技术领域,提供一种航海设备、船舶轴系及其横向振动的控制方法,船舶轴系包括推进轴组件和艉轴组件,推进轴组件包括推力轴,推力轴延伸至艉轴组件;艉轴组件包括艉管和外筒,艉管套设在推力轴的外侧表面;外筒套设在艉管的外侧表面;外筒和艉管之间设有摩擦阻尼耗能结构,摩擦阻尼耗能结构包括摩擦阻尼套筒和摩擦阻尼套环,摩擦阻尼套筒上设有预紧部,摩擦阻尼套环间隔套设于预紧部,摩擦阻尼套环上还阵列设有叠堆压电陶瓷。当船舶轴系受到横向振动时,堆叠压电陶瓷施加预紧力,使艉管的外表面与摩擦阻尼套筒的内表面相互摩擦,产生能量耗损,抑制船舶轴系的横向振动。
