ADAPTIVE SHUNT CIRCUIT FOR SUPPRESSING VIBRATION OF STRUCTURE AND METHOD FOR OPERATING THE SAME

摘要

PURPOSE: An adaptive shunt circuit for suppressing the vibration of a structure and a method for operating the same are provided to suppress the vibration of the structure by changing the characteristics of the circuit in response to the change of the natural frequency. CONSTITUTION: An adaptive shunt circuit for suppressing the vibration of a structure includes a converting block(100) for converting the vibration energy of the structure into an electrical signal, a resonance block(200) for amplifying the electrical signal, a frequency varying block(300) for varying the electrical central frequency of the resonance block(200) in response to the order voltage applied from outside, a power supply block(400) for supplying a power to the converting block(100), the resonance block(200) and the frequency varying block(300).
