Problems solved by technology

However, when the source vibrates at the resonant frequency, even if the device tries to achieve attenuation, it cannot effectively achieve attenuation due to the large amplitude resulting from the resonance, resulting in a loss of electrical energy required to attempt attenuation

Abstract

The present invention provides a vibration damping apparatus actively damping vibration of a vibration source by adding vibration to the vibration source includes a vibrational state detecting means and a vibrator including a magnetic pole, a coil, and a controlling means, and the vibrator adds vibration to the vibration source by controlling a current-supplied state of the coil to vibrate the coil and the magnetic pole relatively, wherein the controlling means selectively switches a vibration generating mode and a regenerative mode based on the vibrational state of the vibration source, the vibration is added to the vibration source to damp the vibration of the vibration source in the vibration generating mode, and regenerative current is caused by an electro motive force generated at the coil by the vibration of the vibration source to flow into a regenerative resistor in the regenerative mode.

Description

technical field [0001] The present invention relates to a vibration damping device for actively damping the vibration of a vibration source by generating additional vibration (vibration) to the vibration source. Background technique [0002] When a structure vibrates, such as a machine with a motor or an electric motor, or a building vibrates, the vibration damping device performs vibration damping by adding an antiphase vibration of the vibration. For example, the vibration damping device disclosed in JP2005-299832A uses an electromagnetic actuator to add anti-phase vibration to the vibration generated in the engine as a vibration source. In addition, the vibration damping device is designed to attenuate vibrations according to the operating state of the engine. That is, different methods are selected for attenuating low-frequency vibrations and high-frequency vibrations, and the vibration-damping device drives the electromagnetic actuator based on a signal derived from th...
