Abstract

The present invention provides a dynamic vibration absorbing device with power generation function, which includes a guide sleeve 4 , a cylinder body 5 , a threaded screw 12 , and a screw nut 14 . Since the inerter has the effect of amplifying the mass attribute, the device of the present invention can be used for vibration reduction of large-scale main vibration systems, and because the wire cuts the magnetic induction line to generate electromagnetic damping, the vibration absorption frequency band is effectively widened, so that the vibration reduction effect reaches the best At the same time, it converts vibration energy into usable electric energy, which is economical, environmentally friendly and energy-saving.

Description

technical field [0001] The invention relates to a dynamic vibration absorber, in particular to a dynamic vibration absorber with power generation function, which belongs to the technical field of vibration control and also belongs to the technical field of energy conversion. Background technique [0002] In 1928, J. Ormond Royd and others proposed the method of dynamic vibration absorber. The dynamic vibration absorber is also called the tuned mass damper. Its principle is to add a mass spring resonance system to the main vibration system. The reaction force generated by this additional system during resonance can reduce the vibration of the main vibration system. 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 series of such shock absorbers are added, vibrations of different frequencies can also be counteracted. Because ...
