Segmented Active Constrained Layer Damper for Structural Vibration Control

该项目的具体目标是：开发一个分段主动约束层处理的有限元模型。该模型将作为一种设计工具，用于优化特定结构的材料和几何参数。为了验证最近开发的分段有源约束层方法在全尺寸地板上的性能。显然，需要一种可靠和有效的控制技术，可以根据变化的外部参数进行调整。建议的系统将满足所有这些要求。主动控制的分段约束层具有根据外界条件对阻尼器参数进行调节的能力。该系统将很容易安装在新建和现有的结构。它还将具有有限的故障安全能力。受约束的粘弹性层即使在停电的情况下也能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.
