Slope Mode and Energy - Transfer Sensors for Nondestructive Evaluation

9360609陈传统的结构评估方法往往不能准确地测量大型民用基础设施的缺陷。该项目引入了结构动力学方面的理论和实验专业知识以及振动传感器方面的经验，以研究创新的斜坡模式和模式能量传递传感器和测量系统，使结构的行为评估和健康监测更加可行和准确。最终目标是开发一系列基于新开发的复能量理论的斜率加速度计，这些加速度计还没有商业化。第一阶段的目标是开发加速度计和校准系统，检查用于进行中型结构振动特征分析的模态能量测量方法。本项目中考虑的方法和传感器可能会对传感器行业、桥梁和大型土木工程结构检测中的结构测量和应用产生重大影响。这是SBIR第一阶段项目。***

9360609 Chen Conventional structural evaluation methods often fail to provide accurate defect measurement of large civil infrastructures. This project brings in theoretical and experimental expertise in structural dynamics and experience in vibration sensors to study innovative slope mode and modal energy transfer sensors and measuring systems that could make structural behavior evaluation and health monitoring more feasible and accurate. The ultimate goal is to develop a series of slope accelerometers, which are not yet available commercially, based on a newly developed complex energy theory. The objective in phase one is to develop the accelerometers and calibration systems, to examine methods for modal energy measurements to perform the vibration signature analysis for medium size structures. The methodology and transducers considered in this project may have a significant impact in structural measurements and applications in transducer industries, bridge and large civil engineering structure inspections. This is an SBIR Phase I project. ***
