Title:
制振装置
Document Type and Number:
Japanese Patent JP6935510
Kind Code:
B2
Abstract:
A damping device to suppress or increase vibration of damping target by changing the moment of inertia of the damping target by utilizing the transformation of magnetic fluid is provided. The damping device includes a container 4 attached to a damping target 1, a magnetic fluid 5 which is included in the container 4 and which is freely transformable so as to move a center of gravity of the damping target 1, an electromagnet 6 to transform the magnetic fluid 5 by an excited magnetic field, a power supply unit 7 to supply a current to the electromagnet 6, a sensor 11 to measure displacement and speed of the damping target 1, and a controller 8 to transmit a control signal to the power supply unit 7 based on a measure value of the sensor.
