Electromagnetic-Piezoelectric Composite Vibration Control Device Based on Synchronized Switch Damping Technology

摘要

The present invention discloses an electromagnetic-piezoelectric composite vibration control device based on a synchronized switch damping technology, and relates to the technical field of vibration abatement. An upper rigid frame is arranged at the upper part of a lower rigid frame, an upper guiding component is installed inside the upper rigid frame, a lower guiding component is installed inside a lower rigid component, a guide rod is nested inside the upper guiding component and the lower guiding component, a load platform is fixed to the upper end of the guide rod, an upper idler wheel mechanism and a lower idler wheel mechanism are fixedly sleeved on the guide rod and are positioned between the upper guiding component and the lower guiding component respectively, an electromagnetic mechanism is fixedly sleeved outside the guide rod, an elastic component is sleeved outside the lower idler wheel mechanism, one end of each piezoelectric cantilever beam is fixed between the upper rigid frame and the lower rigid frame, the other end of each piezoelectric cantilever beam is arranged between the upper idler wheel mechanism and the lower idler wheel mechanism, and the piezoelectric cantilever beams and the electromagnetic mechanism are connected with a circuit system respectively. The device is simple in structure and reliable in performance, a voltage source does not need to be provided externally, and the device is of an adaptive characteristic.
