The invention discloses a chained panel vibration reduction base based on an impedance mismatch principle. The vibration and noise reduction base for the ship mechanical equipment is based on the impedance mismatch principle and comprises a chain type panel, a lateral force prevention spring damper and a bottom plate, the chain type panel is formed by connecting a panel hinge device with a chain type substructure panel in series, and the lateral force prevention spring damper is fixedly installed between the chain type panel and the bottom plate; the chained panel is constructed based on the impedance mismatch principle, mechanical equipment is installed on the chained panel, the chained panel and the base bottom plate are connected through the lateral force prevention spring shock absorber, vibration energy is subjected to dual attenuation of the chained panel and the lateral force prevention spring shock absorber, and the influence of operation of the mechanical equipment on a ship body structure is greatly reduced. The damping device is simple in structure, good in damping performance, good in economical efficiency and wide in application prospect.
