Efficient vibration reduction and isolation base supported by chained panel fluid bladder
The present disclosure provides an efficient vibration reduction and isolation base supported by a chained panel fluid bladder, including a chained panel, the vibration reduction fluid bladder, vertical limiting devices and a bottom plate. The chained panel is a discontinuous structure formed by connecting chained substructure panels in series by panel hinge devices. The vibration reduction fluid bladder and the vertical limiting devices are fixedly installed between the chained panel and the bottom plate. The chained panel is constructed based on the impedance mismatch principle and provided with a mechanical device. Mechanical vibration energy is dissipated twice by the chained panel and the vibration reduction fluid bladder, thereby greatly reducing influences of mechanical device operation on a hull structure. The present disclosure abandons a traditional base design of a continuous panel, is simple in structure and good in vibration reduction performance, and has good economy and wide application prospects.
1. An apparatus, comprising:
a chained panel configured to attach to a mechanical device,
a bottom plate, and
a fluid bladder and vertical limiting devices between the chained panel and the bottom plate, and the vertical limiting devices surrounding the fluid bladder;
wherein the chained panel comprises panel hinge devices and chained substructure panels;
wherein the chained substructure panels are connected in series through the panel hinge devices.
2. The apparatus according to claim 1 , wherein at least one of the vertical limiting devices comprises a top cover plate, a fixing holder, a connection guide pillar and a pedestal, wherein the top cover plate is attached to one chained substructure panel of the chained substructure panels, wherein the pedestal is attached to the bottom plate, and wherein the fixing holder and the connection guide pillar are configured to limit displacement between the one chained substructure panel and the bottom plate in a vertical direction.
3. The apparatus according to claim 2 , further comprising a sleeve between the fixing holder and the connection guide pillar, and a lifting limiting baffle at a bottom end of the connection guide pillar.
4. The apparatus according to claim 1 , wherein the fluid bladder is rectangular.
