The invention provides a mass and rigidity adjustable cabin raft vibration isolation device which comprises a connecting piece, a groove plate, a raft frame, a T-shaped groove plate and a connecting piece which are sequentially connected, the raft frame is of a plate lattice structure formed by welding I-shaped structures, and a batten structure is arranged in the middle of any two adjacent I-shaped structures on the lower surface in the length or width direction of the raft frame. The mass block is installed in the raft frame through a batten structure. And the mass block is connected with the batten structure through a connecting bolt. The floating raft is high in universality, the quality and rigidity of the floating raft and the installation position of equipment can be rapidly adjusted according to the characteristics and requirements of the controlled equipment, the performance of the floating raft is matched with the acoustic requirements of equipment installation, the vibration isolation effect of the floating raft is optimal, and the vibration transmission control requirements of different equipment of a ship are met.

    本发明提供一种质量及刚度可调的舱筏隔振装置,包括依次连接连接件、槽板、筏架、T槽板和连接件,筏架是由工字结构焊接成板格状结构,沿筏架长度或宽度方向的下表面任意两相邻工字结构中间位置布置一板条结构,质量块通过板条结构安装于所述筏架内。质量块与板条结构之间通过连接螺栓连接。本发明通用性强,可根据被控制设备的特点和要求快速调整浮筏自身质量和刚度,以及设备安装位置,实现浮筏性能和设备安装声学要求相匹配,使浮筏隔振效果达到最优,满足船舶不同设备振动传递控制需求。
