Efficient vibration reduction and isolation base supported by chained panel fluid bladder

Abstract

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.
