Enhancing the NEES Geotechnical Centrifuge at UC Davis

该奖项为加州大学戴维斯分校(UCD)提供资金，以升级小乔治·E·布朗的实验能力。位于UCD的地震工程模拟网络(NEES)土工离心机设施，将由NEES Consortium，Inc.运营，作为2005财年至2014财年的国家共享设施。UCD NEES现场的主要设备包括9米土工离心机、2D振动器、飞行机器人、铰接板集装箱、柔性剪切梁集装箱、大量换能器、成像设备和分布式高速无线数据采集系统。根据该合同，将为该站点购买以下设备：无线主无线电、功放和研究人员PC工作台。该站点的第二台主无线电将用于模型准备区域，使NEES研究人员能够与无线通信模块/传感器管理器通信，而不需要在离心机上进行正在进行的实验。它将使研究人员能够在实验室中校准传感器，并在1G测试过程中获取数据，如合并。该系统将保持与网络的连接，以支持远程培训，以便研究人员能够学习独立于主要离心机系统使用软件和硬件。UCD将购买96个放大器模块，以支持模型试验中使用的应变计、称重传感器、位移传感器和其他各种传感器。这两台平板电脑将在模型准备和测试期间供研究人员使用。这些平板电脑将配置软件，通过无线网络访问离心机数据采集系统以及数据存储库和现场规格数据库。该设备将通过NEES联合体公司，UCD NEES设施提供给地震工程研究界。该奖项由NSF NEES重大研究设备和设施建设(MREFC)项目资助，是国家减少地震灾害计划(NEHRP)的一部分。

This award provides funding to the University of California, Davis (UCD), to upgrade the experimental capabilities of the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) geotechnical centrifuge facility at UCD that will be operated by NEES Consortium, Inc., as a national shared use facility during FY 2005 - FY 2014. The major equipment at the UCD NEES site includes the 9-meter geotechnical centrifuge, 2D shaker, in-flight robot, hinged plate container, flexible shear beam container, large inventory of transducers, imaging equipment, and distributed high-speed wireless data acquisition system. Under this award, the following equipment will be purchased for this site: wireless master radio, amplifiers, and researcher PC worktablets. The master radio, the second one at this site, will be used in the model preparation area to enable NEES researchers to communicate with the wireless communication module/sensor manager independently of ongoing experiments on the centrifuge. It will enable researchers to calibrate sensors in the lab and take data during 1g testing processes such as consolidation. This system will be left connected to the network to support remote training so that researchers can learn to use the software and hardware independently of the primary centrifuge system. UCD will purchase 96 amplifier modules to support strain gauges, load cells, displacement sensors, and other miscellaneous transducers that will be used in model testing. The two tablet PCs will be available for use by researchers during model preparation and testing. These tablet PCs will be configured with software to access the centrifuge data acquisition systems, as well as the data repository and site specifications database via the wireless network. This equipment will be available to the earthquake engineering research community through the NEES Consortium, Inc., UCD NEES facility. This award is funded by the NSF NEES Major Research Equipment and Facilities Construction (MREFC) project and is a component of the National Earthquake Hazards Reduction Program (NEHRP).
