Engineering Research Equipment Grant: Automated Vibration and Environmental Control System for Material and Structual Damping Research

该项目支持采购加强材料和结构阻尼研究所需的设备。目标是提高对被动阻尼现象的理解，这是结构行为中最不为人所知的特征之一。主要的研究项目涉及开发用于模拟频率相关动态行为和高阻尼结构材料的有限元分析技术，以及用于测量非常低频率下单个结构元件阻尼的技术。该设备也有可能用于相关项目。该设备由实验控制计算机、智能仪器、无干扰力和运动传感器以及用于研究精密结构动力特性及其对温度、频率、幅值和环境压力的依赖关系的实验室仪器组成。

This project supports the procurement of equipment needed to enhance research on material and structural damping research. The goal is to improve the understanding of the phenomenon of passive damping, one of the most poorly understood characteristics of structural behavior. The primary research projects address the development of finite element analysis techniques for modeling frequency dependent dynamic behavior and high damping structural materials, and techniques for measuring damping of individual structural elements at very low frequencies. There is the potential for using the equipment on related projects as well. The equipment comprises an experiment control computer, intelligent instruments, non interfering force and motion transducers, and laboratory apparatus for studying precision structural dynamic behavior and its dependence on temperature, frequency, amplitude, and ambient pressure.
