<p><P>PROBLEM TO BE SOLVED: To provide an active type dynamic vibration absorber which obtains a desirable dynamic range and further improves performance while reducing costs. <P>SOLUTION: This active type dynamic vibration absorber includes: a weight 2; a framework 3 arranged adjacent to the weight 2, and surrounding the weight 2 with clearances X1 and Y1; a holding mechanism 4 interposed between the weight 2 and the framework 3 to hold the weight 2 movably in a direction X relative to the framework 3, and preventing the movement thereof in a direction Y and the vertical direction V; a detecting means 5 for detecting a predetermined value of relative vibration of the weight 2 in the direction X relative to the framework 3; and a moving means 6, which allows the movement of the weight 2 relative to the framework 3 in the direction X based on a signal detected by the detecting signal and, on the other hand, which moves the weight 2 in the direction X relative to the framework 3 so as to reduce the displacement of the vibration of the weight 2 in the direction X relative to the framework 3. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
