DESIGN METHOD OF VIBRATION DAMPING DEVICE WITH FAILSAFE
PROBLEM TO BE SOLVED: To reduce a size of a device.SOLUTION: In a design method of a vibration damping device with failsafe having a first TMD vibration damping device which has a first suspension pendulum having a first suspension length, and a first inversion pendulum having a first inversion length, and suppresses the oscillation of a vibration damping object, and a failsafe device which is arranged between the vibration damping object and the first TMD vibration damping device and comprises a trigger mechanism, the vibration damping device comprises a second TMD vibration damping device having a second suspension pendulum having a second suspension length and a second inversion pendulum having a second inversion length. A non-failsafe vibration damping device for suppressing the oscillation of the vibration damping object without having failsafe is designed, a total value of mass bodies of the first suspension pendulum and the first inversion pendulum and a total value of mass bodies of the second suspension pendulum and the second inversion pendulum are made equal to each other, the first suspension length is set shorter than the second suspension length, and the first inversion length is set longer than the second inversion length.SELECTED DRAWING: Figure 7
