中文摘要
0408578 PI:维克托GiurgiutiuUniv南卡罗来纳州本提案涉及主动传感器的结构健康监测。所考虑的特定类型的传感器是压电晶片有源传感器(PWAS)。拟议的研究解决了兰姆波之间的PWAS传感器和主机结构的相互作用的基本方面。我们的目标是开发一个预测的方法优化设计的传感器。主要包括三个问题:1.微机械耦合的各种兰姆模式,2。宽带PWAS换能器的兰姆波调谐,以及3。PWAS传感器的原位导抗和最佳功率流。在本研究项目中嵌入了一个平衡良好的教育增强组件。
英文摘要
0408578PI: Victor GiurgiutiuUniv South CarolinaThis proposal deals with structural health monitoring with active sensors. The particular type of sensors considered is the piezoelectric wafer active sensors (PWAS). The proposed study addresses fundamental aspects of the Lamb-wave interaction between the PWAS transducers and the host structure. The objective is to develop a predictive methodologies for optimum design of such sensors. Three main issues are included: 1. Micromechanical coupling for various Lamb modes, 2. Lamb-wave tuning with broadband PWAS transducers, and 3. in-situ immittance pf PWAS transducers and optimal power flow.A well-balanced educational enhancement component is embedded in this research project.
