MULTI-DIMENSIONALLY SYNCHRONIZED PASSIVE VIBRATION CONTROL DEVICE AND ACTIVE VIBRATION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a multi-dimensionally synchronized passive vibration control device capable of synchronizing a vibration-control object with a natural frequency of perpendicularly or crossing two axes by using a piece of vibration control mass body. ;SOLUTION: The multi-dimensionally synchronized passive vibration control device is comprised of vibration control mass body M, a vibration control object 2, and a plurality of supports S arranged between the vibration control mass body M and the vibration control object 2 for supporting the vibration control mass body M from different directions. In this case, each support S is comprised of a flexible part 1 for a shear direction with high rigidity against force applied in an axial direction of the support S and low rigidity against force applied in a shear direction, and a flexible part 3 for an axial direction with low rigidity against force applied in an axial direction of the support S. Accordingly, the flexible part 1 and 3 of the supports S can synchronize with vibration inputted from the flexible directions.;COPYRIGHT: (C)2000,JPO
