【発明の詳細な説明】 本発明は減衰器として粘弾性体又は粘性体を使
用した板バネ式動吸振器に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plate spring type dynamic vibration absorber using a viscoelastic body or a viscous body as a damper.

まず、動吸振器の基本原理について説明する。 First, the basic principle of a dynamic vibration absorber will be explained.

合で、共に応答振幅は大きい。Cd＝Cd Once the size of the structure (mass, rigidity, etc.) and the mode shape of the target vibration are known, the following three characteristic values are determined, which are sufficient to express the characteristics of the vibration. This can be shown as a model as shown in Figure 1. In the figure, M T is the equivalent mass of the structure (ts 2 /m),
K T represents the equivalent spring (t/m) of the structure, and C T represents the equivalent damping (ts/m) of the structure. This structure has a mass
Fig. 2 shows a model of the state in which a dynamic vibration absorber having vibration characteristic values of M d , spring K d , and damping C d is attached. However, the change in the resonance curve of the structure to which this dynamic vibration absorber is installed (the damping coefficient C d of the dynamic vibration absorber)
Figure 3 shows the same model when . In Figure 3,
The vertical axis is the response magnification, and the horizontal axis is the external frequency ω p /natural frequency ω T . In Figure 3, the curve C d = 0 is for a state where there is no damping of the dynamic vibration reducer, and the curve C d = ∞ is for a state where the mass M d of the dynamic vibration absorber is fixed to the mass M T of the structure, both of which are The response amplitude is large. C d = C d
