The invention relates to the technical field of ship bottom plate manufacturing, and discloses a friction stir welding aluminum alloy ship bottom plate which comprises an outer protection plate and an inner protection plate, the outer protection plate and the inner protection plate are both plates of an arc-shaped structure, the inner protection plate is arranged in the outer protection plate, a gap is formed between the outer protection plate and the inner protection plate, and the inner protection plate is arranged in the gap. A bottom plate is arranged on the top face of the outer protection plate and the top face of the inner protection plate, first welding openings in bilateral symmetry are formed in the positions, close to the upper side, of the side wall face of the inner protection plate in a penetrating mode, second welding openings in bilateral symmetry are formed in the top face of the bottom plate in a penetrating mode, and a welding part is arranged at the connecting position of the inner protection plate and the bottom plate. A welding part is also arranged at the joint of the outer protection plate and the bottom plate, and the outer protection plate and the bottom plate are fixedly spliced together through friction stir welding. According to the device, the shaking amplitude and the stress direction of the peripheral elastic particles and the short fiber materials are sensed through the multiple sets of sensors, and the effect of rapidly positioning the collision position is achieved.

    本发明涉及船舶底板制作技术领域,且公开了一种搅拌摩擦焊铝合金船舶底板,包括外防护板和内防护板,所述外防护板和内防护板均为弧形结构的板,所述内防护板设置在外防护板的内部,外防护板和内防护板之间形成间隙,所述外防护板和内防护板的顶面设置有底板,所述内防护板的侧壁面靠近上侧位置处贯穿开设有左右对称的焊接口一,所述底板的顶面贯穿开设有左右对称的焊接口二,所述内防护板与底板的连接位置处设置有焊接部,所述外防护板与底板的连接处同样设置有焊接部,通过搅拌摩擦焊接使外防护板与底板固定拼接在一起。本发明中,通过设置的多组感应器感应到周边弹性颗粒和短纤维丝材料的晃动幅度和受力方向,达到了快速定位碰撞位置的效果。
