Segmented Active Constrained Layer Damper for Structural Vibration Control

本项目的具体目标是：开发分段主动约束层治疗的有限元模型。该模型将被用作设计工具，以优化针对特定结构的处理的材料和几何参数。为了验证最近开发的分段主动约束层法在全尺寸楼板上的性能，显然需要可靠而有效的控制技术来适应不同的外部参数。拟议的系统将满足所有这些要求。主动可控分段约束层具有根据外界条件调整阻尼器参数的能力。该系统将很容易安装在新建和现有结构中。它还将具有有限的故障安全功能。即使在停电的情况下，约束粘弹性层也会提供一定程度的阻尼。

The particular objectives of this project are: To develop a finite element model of a Segmented Active Constrained Layer treatment. That model will be used as a design tool to optimize material and geometrical parameters of a treatment for a particular structure. To demonstrate the performance of recently developed Segmented Active Constrained Layer method on a full-size floor.Clearly, there is a need for reliable and effective control technique that could adjust to varying external parameters. All these requirements will be satisfied by the proposed system. Actively controlled-segmented constraining layer has the capability of adjusting damper parameters to the external conditions at hand. The system will be easy to install both in newly constructed and in existing structures. It will also have a limited fail-safe capability. The constrained viscoelastic layer will provide a certain level of damping even in the case of power failure.
