Problems solved by technology

The disadvantage of these two tuned mass dampers is that the energy recovered is relatively small, because the main goal of these structures is to supply power only for vibration control, based on semi-active systems
Moreover, because tuned mass dampers are suitable for construction engineering structures, these devices do not have tight characteristics, which is not conducive to miniaturization

Embodiment

[0040] Take a main structure with a mass of 40 kg and a stiffness of 157,880 N / m as an example, which is exposed to harmonic vibrations with an amplitude of 0.005 m and a frequency of 62.8 rad / s, which is equal to the natural frequency of the structure. To protect this structure from damage, the electromagnetic vibration recovery energy tuned mass damper of the present invention is used. According to the optimal theoretical vibration suppression effect of the tuned mass damper, the structural parameters of the tuned mass damper selected in this embodiment are as follows: the mass is 8 kg, the stiffness is 21752 N / m, and the damping parameter is 219 N*sec / m.

[0041] Because the rare earth permanent magnet material FeNdB grade N52 has high residual magnetic flux density and economy, it is selected as the material of the ring magnet assembly. The material of the bottom ferromagnet and the upper ferromagnet is selected from low carbon steel 1010, which has a comparable magnetic p...

Abstract

The invention discloses an electromagnetic vibration recovered energy tuned mass damper. The tuned mass damper comprises a ferromagnet magnet ring assembly, a spring assembly and a coil assembly. Theferromagnet magnet ring assembly is composed of an upper magnet, an annular magnet component and a bottom ferromagnet. The coil assembly is composed of a coil, an auxiliary rod and a basic flange. Thespring assembly is composed of an upper flange, a spring and a lower flange. The spring assembly is connected with the upper ferromagnet through upper bolts, and is connected with a structure (main structure) needing vibration elimination through lower bolts. Therefore, relative motion between the coil and the ferromagnet magnet ring assembly is generated by vibration of the main structure, and then electromotive force inside a wire is created. The electromagnetic vibration recovered energy tuned mass damper not only can eliminate vibration, but also can recover vibration energy to use as electric power.

Description

technical field [0001] The invention belongs to the technical field of mechanical vibration suppression and energy collection, and relates to a tuning mass damper, in particular to an electromagnetic vibration recovery energy tuning mass damper. Background technique [0002] Due to the lack of fossil fuels, energy harvesting technologies are becoming more and more important. Basically, energy harvesting technology is divided into the following four directions: electromagnetic, piezoelectric, electrostatic, hot spot type. [0003] Electromagnetic energy harvesting technology is based on vibration energy and resonance effect. The basic concept is to install the energy recovery device to the main structure, and then the vibration collected by the main structure is transmitted to the energy recovery device, so it reaches the resonance frequency. From then on, the device uses electromagnetic power generation Faraday. The principle converts vibrational energy into electromagnetic...
