Problems solved by technology
[0004] However, there are many defects in traditional dynamic vibration absorbers. The main manifestations are: on the one hand, the effective vibration reduction frequency band of the vibration absorber is very narrow, and once the tuning is lost, the vibration reduction effect will be significantly deteriorated; new formant, thereby exacerbating the main system vibration

Description
technical field [0001] The invention relates to a dynamic vibration absorber, in particular to a novel dynamic vibration absorption method and system. Background technique [0002] The dynamic vibration absorber is a kind of equipment that uses the resonance system to absorb the vibration energy of the object to reduce the vibration of the object. It is currently widely used in the vibration control of mechanical systems, engineering structures, bridges and buildings. [0003] Please refer to Figure 1a , Figure 1b , The working principle of the traditional dynamic vibration absorber is: attach a mass spring resonance system to the vibrating object, and the reaction force generated by this additional system during resonance can reduce the vibration of the vibrating object. Dynamic vibration absorbers are especially useful when the excitation force is dominated by a single frequency, or when the frequency is very low, and general vibration isolators are not suitable. If a ...
