摘要:
针对目前磁流变减振器需要外部电能输入的问题,该文利用压电振动能量捕获技术设计了一种无需外部电能输入的自供电磁流变减振器。论述了该自供电磁流变减振器的结构及其压电能量捕获理论模型,设计加工了自供电磁流变减振器的器件原型,并在实验台架上对其进行实验验证。结果表明:在外界振动作用下,该自供电磁流变减振器可以在无需外界电能输入的条件下改变阻尼特性,实现磁流变减振器的自供电功能。
Abstract:
Regarding the problem that the external power supply is required in the current magneto-rheological(MR) damper system,a self-powered MR damper is designed based on the piezoelectricvibration energy harvesting technology. The structure and dynamic equation for the self-powered MRdamper are derived. A prototype is fabricated and tested to evaluate the vibration isolation capabilityof the self-powered MR damper. The test results show that, under the outside vibration, the self-powered MR damper can collect the electric energy to activate electromagnetic coils inside thedamper,change its damping characteristics,and achieve the self-powered function.
