为了减少声音和振动在木结构建筑等结构中的传递,可以在其部件之间嵌入薄弹性体层。这些弹性体的影响,在低频范围内的结构的响应,可以准确地确定通过使用协调六面体有限元。然而,三维网格生成仍然是一项重要的任务,并且在接合处可能需要的网格细化可能会导致高计算量。一种补救方法是将组件彼此独立地网格化,并使用砂浆方法耦合它们。此外,薄弹性体层本身的六面体网格可以通过将其弹性行为整合到砂浆配方中来避免。本文扩展了砂浆配方考虑阻尼,这样可以更准确地进行频率响应分析。最后,通过数值算例验证了该方法的有效性.
In order to reduce the transfer of sound and vibrations in structures such as timber buildings, thin elastomer layers can be embedded between their components. The influence of these elastomers on the response of the structures in the low frequency range can be determined accurately by using conforming hexahedral finite elements. Three-dimensional mesh generation, however, is yet a non-trivial task and mesh refinements which may be necessary at the junctions can cause a high computational effort. One remedy is to mesh the components independently from each other and to couple them using the mortar method. Further, the hexahedral mesh for the thin elastomer layer itself can be avoided by integrating its elastic behavior into the mortar formulation. The present paper extends this mortar formulation to take damping into account such that frequency response analyses can be performed more accurately. Finally, the proposed method is verified by numerical examples.
