However, in the above honeycomb panel, attention is paid to the known excellent vibration suppressing effect of the aluminum vibration damping plate itself, and this known aluminum vibration damping plate is simply used for the upper and lower surfaces of the honeycomb core. Since the structure is attached to at least one side, there is some improvement in the vibration suppression effect compared to when only the aluminum plate is adhered, but the vibration suppression effect for the honeycomb panel as a whole is There is a problem that it is lower than that when used alone.

According to the first aspect of the invention, the viscoelastic material layer is located near the neutral axis of the honeycomb panel, and the bending rigidity of each of the honeycomb structure above and below the viscoelastic material layer is adjusted. Can be about equal. As a result, the viscoelastic material layer can exert the same action as the mechanical characteristic that acts on the synthetic resin layer positioned on the neutral axis when a known aluminum damping plate is used alone. That is, when the entire honeycomb panel is subjected to bending deformation, the viscoelastic material located near the neutral axis of this panel is also subjected to shear deformation, but since the shear strain energy becomes maximum, the vibration energy is converted into thermal energy and the outside air is converted. The rate of release to the maximum is also maximized, and the effect of suppressing vibration of the entire panel is maximized.

This point is largely different from the operation of the conventional vibration damping honeycomb panel. That is, in the conventional honeycomb panel, a known aluminum damping plate is simply used as the face material of the honeycomb core, and since the bending rigidity of the honeycomb core is large, the synthetic resin of the aluminum damping plate is It will be located far away from the neutral axis. As a result, the shear strain energy generated in the synthetic resin is extremely smaller than the shear strain energy acting on the synthetic resin when using a single aluminum damping plate, and the rate at which vibration energy is converted to thermal energy, that is, vibration damping The rate could not be increased, and the effect of suppressing vibration of the entire honeycomb panel was not improved.

Next, in the second invention, the bending rigidity of the thick elastic body on the non-honeycomb core side of the viscoelastic material layer is the bending rigidity of the honeycomb core using the thin elastic body on the honeycomb core side as a so-called face material. It is possible to approach. That is, as a result, the viscoelastic material can be brought close to the neutral axis of the honeycomb panel. In this case as well, the viscoelastic material becomes the viscoelastic material when the entire honeycomb panel is subjected to bending vibration as in the invention of claim 1. The shear strain energy generated becomes very large, and the vibration damping effect can be greatly improved by increasing the vibration damping rate.

Next, the operation of the third invention will be described. First, looking at how the vibration is transmitted in the conventional honeycomb panel, the panel is vibrated by receiving sound pressure from a noise source or mechanical vibration. At this time, the side wall of the honeycomb core is significantly deformed near the joint with the face plate. However, the honeycomb core does not take any vibration suppression measures, and relies on the face plate vibration suppression measures.

On the other hand, the third aspect of the present invention is a honeycomb panel having a structure in which a viscoelastic material film is attached to all sidewalls of a honeycomb core. Therefore, the bending generated on the side wall of the honeycomb core is converted into thermal energy at the viscoelastic material film on the front and back surfaces of the side wall of the honeycomb core by expansion and contraction of the viscoelastic material due to bending vibration, and is released to the outside air. As a result, the vibration suppressing effect of the entire honeycomb panel is significantly improved.

Are integrally laminated and formed. In this structure, the honeycomb structures 11a and 11b, which occupy the upper and lower two layers in the drawing, form a rigid panel by attaching aluminum plates 13a and 13b having the same thickness to the upper and lower surfaces of the aluminum honeycomb core 12 having the same thickness, respectively. There is.

When vibration is applied to the damping honeycomb panel 10, the upper and lower two rigid panels 11a and 11b are
Start bending vibration. At this time, the resin sandwiched between the two rigid panels 11a and 11b undergoes shear deformation, but since the resin layer 14 exists near the neutral axis of the damping honeycomb panel 10, the shear strain energy of the resin becomes maximum. The efficiency of heat generated by the resin layer 14 and released to the outside is maximized. As a result, the damping honeycomb panel 10
The overall effect of suppressing bending vibration is maximized.

The vibration suppressing effect is maximized when the upper and lower two rigid panels 11a and 11b have the same thickness. On the other hand, the increase in the shear elastic modulus of the resin has a negative effect on the bending rigidity. Therefore, the bending rigidity of the entire vibration-damping honeycomb panel 10 tends to slightly decrease. Therefore, in applying each industrial field, in consideration of the balance between the required bending rigidity and the required vibration suppression effect amount, the configuration of the present embodiment is adopted as it is, or the rigid panels 11a of the upper and lower two layers,
An appropriate difference is made in the thickness of 11b to position the resin layer 14 at a position slightly deviated from the neutral axis of the entire vibration damping honeycomb panel,
It is possible to appropriately select such a configuration as to ensure a sufficient bending rigidity while maintaining a necessary and sufficient vibration suppressing effect, and this case does not depart from the technical scope of the present invention.

Next, FIG. 2 is a schematic explanatory view of a vibration damping honeycomb panel embodying the second invention. The vibration-damping honeycomb panel 20 includes a thick aluminum plate 21a, a resin layer 23, a thin aluminum plate 21b, which extends from the outside of the panel in the thickness direction.
The aluminum honeycomb core 22, the thin aluminum plate 21b, the resin layer 23, and the thick aluminum plate 21a are integrally laminated and formed in this order.

In this structure, the thicker the aluminum plate 21 is, the larger the ratio (ta / tb) between the thickness (ta) of the thick aluminum plate 21a and the thickness (tb) of the thin aluminum plate 21b is.
The bending rigidity of a can be made close to the bending rigidity of the aluminum honeycomb core 22 having the thin aluminum plate 21b as a surface material,
As a result, the resin layer 23 can be positioned near the neutral axis of the entire vibration damping honeycomb panel 20. Therefore, when bending vibration occurs in the vibration-damping honeycomb panel 20, the shear strain energy of the resin becomes very large as in the case of the embodiment of the first invention, and this resin layer 23 becomes heat and is released to the outside. The efficiency is also greatly increased. As a result, the effect of suppressing bending vibration of the entire vibration damping honeycomb panel 20 can be significantly enhanced.

When vibration from a vibration source is applied to the vibration damping honeycomb panel 30 as described above, the aluminum plate 31a and the resin layer 3 are formed.
4, the face material 31 made of the aluminum plate 31b is excited to start bending vibration, and the vibration energy is the honeycomb core 3
3 propagates to the side wall 33a. At this time, the vibration energy transmitted from the face material 31 through the side wall 33a is converted into heat energy at the resin film 33b on the front and back surfaces of the side wall 33a by expansion and contraction due to bending vibration of the resin, and is released to the space 33c of the honeycomb core. It As a result, the vibration energy transmitted to the face material 31 on the side opposite to the vibration source becomes extremely small, and the vibration suppressing effect of the entire vibration damping honeycomb panel 30 can be significantly improved. Further, as shown in the drawing, one or both of the face materials 31 can be covered with the resin film 32 to further enhance the vibration suppressing effect.
