Semi-active electromagnetic resonant-type tuned mass damper

Abstract

The invention discloses a semi-active electromagnetic resonant-type tuned mass damper. The semi-active electromagnetic resonant-type tuned mass damper comprises a mass block, a permanent magnetic linear generator and a spring; the spring and the permanent magnetic linear generator are perpendicularly arranged below the mass block; the upper ends of the spring and the permanent magnetic linear generator are connected with the mass block by virtue of a connecting member, and the lower ends of the spring and the permanent magnetic linear generator are used for being connected with a controlled structure; and the output end of the permanent magnetic linear generator is connected with an input end of a voltage stabilizer by virtue of a resistance-inductance-capacitance RLC resonant circuit, theoutput end of the voltage stabilizer is connected with an energy storage unit, thereby forming a parallel connection circuit of the permanent magnetic linear generator, the resistance-inductance-capacitance RLC resonant circuit, the voltage stabilizer and the energy storage unit. By adopting the semi-active electromagnetic resonant-type tuned mass damper, multiple effects such as the semi-activecontrol for adjusting the damping force in real time, recycling of vibration energy and electromagnetic turning can be realized. The semi-active electromagnetic resonant-type tuned mass damper has theadvantages of high energy collection efficiency, simple structure, good damping control performance and wide application range.

AI Technical Summary

Benefits of technology

This patented device improves upon existing devices by providing higher energy collecting efficiency, simpler construction, improved vibrational reducing capabilities, wider applicability, and more precise regulation over its operation frequency or amplitude level. It also includes various technical features such as resistors, coils, and controllers used together to achieve optimal vibration suppression levels while minimized interference between different components within it's own system. Additionally, there may include active controls like pendants on top of the device itself to restore stored energy if needed without any outside sources at all times. Overall, this technology provides efficient means for prevention against damage from seismic activity and severe weather conditions.

Problems solved by technology

This technical issue addressed by this patented relates to reducing stress waves transmitted from outside environments overpasses building constructions or other large areas during heavy storm events caused by explosions or tsunamis. Current methods involve adding weight elements called suspended balls (SM) to provide stability against severe environmental disturbances such as impact forces and ground movements. These solutions require expensive equipment and may lead to reduced durability and functionality issues associated with them. Therefore, it would be advancement towards developing a less complicated and efficient way to prevent excessive vibrations generated within buildings while also optimally regulating the dome shaped suspension design based upon external stimuli like temperature changes and structural features.
