Description

[0002] The omnidirectional variable parameter eddy current tuned mass damper is an innovative device applied in the field of vibration reduction technology for engineering structures. Utilizing the principle of eddy currents and a variable parameter design, it can achieve multi-directional tuned vibration control and possesses energy recovery capabilities. Traditional tuned mass dampers generally employ linear dampers and liquid dampers, which have many limitations and shortcomings in terms of vibration reduction effect, energy recovery, and maintenance costs.

[0003] In existing technologies, tuned mass dampers typically use liquid or friction damping and employ a fixed, rigid design, which has many drawbacks. Traditional tuned mass dampers are usually designed for vibrations at specific frequencies, and their vibration reduction effect may be poor at other frequencies, limiting their adaptability. The energy dissipation of traditional tuned mass dampers mainly relies on mechanical friction and liquid viscosity, which are inefficient and cannot achieve efficient energy recovery and reuse. Parameter adjustment of traditional dampers usually requires manual or mechanical adjustment, which is complex and time-consuming. Furthermore, some liquid dampers require periodic liquid replacement, increasing maintenance costs and workload. Summary of the Invention
