Engineering Research Equipment Grant: Multichannel Data Acquisition and Signal Processing

点击翻译按钮获取中文摘要

Funds for the purchase of a multichannel signal processor and an electromechanical shaker are granted. The equipment is required for projects researching the assessment of highway bridge structural integrity from analysis of the vibration signatures; the dynamics of machine tools undergoing rapid change in configuration; the vibrations of earthquake - resistant buildings; aeroelastic testing of bridge decks; and a set of small shaker table studies. Each of these projects requires the multichannel signal processing capability of the requested equipment. The electromechanical shaker will serve as an excitation mechanism and as a small shaker table. The successful completion of these projects could have a significant impact on the maintenance of the nation's highway infrastructure and could produce new machine tool technologies.
