AI Technical Summary
Existing technologies for vibration reduction and noise reduction of marine machinery and equipment have limitations in terms of structural strength, vibration reduction effect, processing technology, installation difficulty and economic cost, making it difficult to design a composite vibration reduction base that is simple in structure, highly stable, has good vibration reduction performance, is flexible in disassembly and assembly and has low cost.
A composite vibration damping base based on surface wave characteristics is adopted, including a base panel, a liquid storage tank, a piston-type spring limiting mechanism, and a diversion box structure. The vibration of the equipment drives the piston-type spring limiting mechanism to generate surface ripples in the liquid in the storage tank, thereby dissipating vibration energy. Combined with the damping layer absorbing sound waves, the vibration damping effect is enhanced.
It achieves significant attenuation of equipment vibration energy in the transmission path, has good vibration reduction performance and economy, has a simple structure that is easy to process, is flexible in disassembly and assembly, improves structural stability, and is suitable for the installation and fixing of various types of equipment on ships.
