The invention provides an acoustic bridge device for transmitting vibration of a second acoustic channel of a mechanical system. The acoustic bridge device comprises a support, a frame type cross beam and an elastic suspension rod. The support comprises a set of supporting columns and a set of cable-stayed reinforcing rod structures matched with the supporting columns, the frame type cross beam comprises a set of transverse beams, longitudinal beams and anti-bending reinforcing beams, and the transverse beams and the anti-bending reinforcing beams are rigidly connected with the longitudinal beams respectively; the elastic suspension rod comprises a group of suspension rods, an elastic suspension element and a pipeline elastic horse foot interface, and the suspension rods are arranged below the frame type cross beam and are elastically connected with the lower surface of the frame type cross beam through the elastic suspension element; the end face and the side face of the tail end of the suspension rod are respectively provided with an installation connector of the pipeline elastic horse foot in a reserved mode. According to the technical scheme, vibration interference of the second sound channel of the ship mechanical system on the first sound channel can be eliminated, and technical support is provided for accurate evaluation of the vibration control effect of the first channel of the mechanical system.

    本发明提供一种传递机械系统第二声通道振动的声桥装置,包括:支架、框架型横梁和弹性悬吊杆。所述支架,包括一组支柱和一组与所述支柱配合的斜拉加强杆结构,所述框架型横梁,包括一组横向梁、纵向梁和抗弯强化梁,所述横向梁和抗弯强化梁分别与所述纵向梁刚性连接;所述弹性悬吊杆,包括:一组悬吊杆、弹性悬吊元件和管路弹性马脚接口,所述悬吊杆布置在所述框架型横梁的下方,通过弹性悬吊元件与所述框架型横梁的下表面弹性连接;所述悬吊杆的末端端面及侧面分别预留所述管路弹性马脚的安装接口。本发明技术方案,能够排除船舶机械系统第二声通道对第一声通道的振动干扰,为机械系统第一通道振动控制效果的精准评估提供技术支撑。
