摘要：
An apparatus includes a damper, a source of magnetic field coupled to the damper, a colloidal ferro-fluidic damping medium disposed in the damper, a sensor installed on the host structure to measure vibrations, and a vibration control circuit. The output of the sensor is fed back to the control circuit, which outputs a command signal to the source of the magnetic field applied to the damper to change the magnetic field in the damper as well as its damping curve so that the dynamic performance of the host structure installed with the damper is changed automatically to yield maximum vibration mitigation.
