<P>PROBLEM TO BE SOLVED: To provide a vibration reducing device and a vibration reducing method, capable of reliably reducing the vibration of an object to be damped. <P>SOLUTION: The vibration reducing device includes elastic bodies 23-1 to 23-2, a dynamic mass 22 to be supported by an object to be damped via the elastic bodies 23-1 to 23-2, a control mass 24, and an actuator 25 for moving the control mass 24 with respect to the dynamic mass 22. The vibration reducing device can fluctuate the frequency and the amplitude of the vibration of the dynamic mass 22 to the object by adequately exercising the control mass 24 with respect to the dynamic mass 22, and the vibration of the object can be reliably reduced. The vibration reducing device can reduce the vibration of the predetermined frequency of the object even when the control mass 24 is fixed to the dynamic mass 22. <P>COPYRIGHT: (C)2011,JPO&INPIT |
