MULTILAYER DAMPING MATERIAL

The invention discloses a multilayer damping material for damping a vibrating surface comprising: at least one constraining layer; at least one dissipating layer; and at least one kinetic spacer layercomprising multiple spacer elements. The kinetic spacer layer is arranged between the constraining layer and the vibrating surface, when used for damping the vibrating surface. Each spacer element has opposite ends. At least one end of each of the multiple spacer elements is embedded in, bonded to, in contact with, or in close proximity to the dissipating layer, such that energy is dissipated within the multilayer damping material, through movement of the at least one end of each of the multiple spacer elements. 用于阻尼振动表面的多层阻尼材料，该多层阻尼材料包括：至少个约束层；至少个耗散层；以及包括多个间隔元件的至少个动力间隔层。当用于阻尼振动表面时，动力间隔层布置在约束层和振动表面之间。每个间隔元件具有相对的端部。多个间隔元件中的每个间隔元件的至少个端部嵌入在耗散层中、结合到耗散层、与耗散层接触或紧紧靠近耗散层，使得能量通过多个间隔元件中的每个间隔元件的至少个端部的移动而在多层阻尼材料内耗散。
