Engineering Research Equipment Grant: Multichannel Data Acquisition and Signal Processing

拨款购买多通道信号处理机和机电式振动筛。从振动特征分析进行公路桥梁结构完整性评价的研究项目需要该设备；经历结构快速变化的机床动力学；抗震建筑的振动；桥面气动弹性试验；和一套小振动台研究。这些项目都需要所需设备具有多通道信号处理能力。机电激振器将用作激励机构和小型激振台。这些项目的成功完成可能对国家公路基础设施的维护产生重大影响，并可能产生新的机床技术。

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.
