である。Generally, a vibration-damping steel plate is a laminated metal plate in which a viscoelastic polymer resin is sandwiched between two metal plates to convert vibration energy into heat energy in the resin to absorb vibration.

る。However, since the viscoelastic properties of the entrapped polymer resin change depending on the temperature, the vibration damping property shows temperature dependence, and the applicable applications are limited. Further, since the polymer resin is inferior in heat resistance, when welding is performed, it is necessary to remove the resin in that portion, which is a great limitation in use.

ことを見い出し、ここに本発明をなしたものである。Means for Solving the Problems As a result of intensive studies to solve the above-mentioned various problems, the inventors of the present invention have formed a metal plate with one layer or two or more layers on one side or both sides. It has been found that high vibration damping property and heat resistance capable of withstanding various uses can be obtained for the first time by controlling the gap size between each layer and the area ratio thereof when partially joining by bolt bonding. It was made.

ものである。That is, the present invention has a structure in which a metal plate is laminated in one layer or two or more layers on one side or both sides of a metal plate, and the area ratio in which the gap between the layers is 50 μm or less is 70%.
The gist is a laminated metal plate having excellent vibration damping performance and heat resistance, which is characterized by being bolted as described above.
【００１２】以下に本発明を更に詳述する。The present invention will be described in more detail below.

【００１４】本発明による積層金属板は、空気層を利用
した積層板や介在物などを介在させた拡散接合型金属板
と比較して、接合間隔が長いため、金属板間の摩擦エネ
ルギー吸収量が大きくなり、高い制振性が得られる。The laminated metal sheet according to the present invention has a longer joining interval as compared with a diffusion-bonded metal sheet having an air layer, or a diffusion-bonded metal sheet having inclusions, so that the friction energy absorption amount between the metal sheets is large. Is increased, and high vibration damping property is obtained.
【００１５】このためには、金属板の片面又は両面に、
１層又は２層以上で金属板をボルト接合により部分接合
する。To this end, on one or both sides of the metal plate,
Metal plates are partially joined by bolt joining in one layer or two or more layers.
【００１６】しかし、金属板の隙間が５０μmを超える
場合、金属板間の摩擦が小さくなり、制振性が低下す

うな隙間を有する部分(接合部分)は各層間において均一
に或いは等間隔に分布しているのが望ましい。However, when the gap between the metal plates exceeds 50 μm, the friction between the metal plates becomes small and the vibration damping property deteriorates. For this reason, the gap between the metal plates needs to have a minimum area ratio of at least 50 μm or less. In that case, the area ratio where the gap between the metal plates is 50 μm or less is 70%
When it is less than 1, the friction area between the metal plates for enhancing the vibration damping property becomes small and the vibration damping property is deteriorated. Therefore, in the laminated metal plate according to the present invention, the area ratio in which the gap between the layers is 50 μm or less needs to be 70% or more. It should be noted that it is desirable that the portions having such gaps (joint portions) be evenly or evenly distributed between the layers.

は、１層でも２層以上でもよい。Although the number of metal plates of each layer to be bolt-bonded may be one, a plurality of metal plates can be divided and used, and a higher vibration damping property can be obtained. This is because the rigidity of the metal plate to be joined to the original metal plate is different and the vibration curvature changes, so that energy absorption due to friction between the metal plates increases and high vibration damping property is obtained. Of course, the metal plate to be divided may be one layer or two or more layers.

Further, as the metal plate, not only a steel plate but also any metal plate can be used, and different kinds of metal plates can be joined together.
The plate thicknesses of the metal plate to be joined and the laminated metal plate can be appropriately determined.

At that time, the gap between the metal plates was controlled to have various values.

Note that FIG. 3 is a diagram showing the relationship between the loss coefficient and the area ratio in which the gap between the steel plates is 50 μm or less. From this, it can be seen that when the area ratio in which the gap is 50 μm or less is less than 70%, the vibration damping property is significantly reduced.
