Acquisition of a Closed-Loop Hydraulic Loading System and Data Acquisiton System for Research and Teaching in Structural Engineering (MRI/RUI)

本文将研制一套闭环液压加载和电子数据采集系统。该系统将提供在静态、循环或动态载荷条件下对结构材料和结构构件进行载荷控制或位移控制试验的能力。数据采集系统将与液压加载系统一起使用，并允许同时监测80个通道的数据（应变、载荷、位移等）。所要求的设备是对PI目前使用的测试系统的重大升级。目前的加载系统仅限于静态测试，手动开环系统只能施加载荷，不能控制载荷。目前的数据采集设备在扫描速度和精度方面受到限制，无法适应动态测试。工程学院正在实施一项七年战略计划，结构工程被列为重点领域，重点将放在基础设施的支持和发展上。与此计划相结合，一个新的9500平方英尺的结构工程研究和教学实验室计划于2004年在校园内开放。本提案中要求的测试系统在设计时考虑到了这一点，因为该设备将在现有实验室和新设施中使用。设计的系统也很容易安装，以适应长期的需求。通过各种机制，本科生将有机会使用所需的设备进行研究。代表性不足的群体将受益于工程学院继续致力于为这些群体提供工程教育的机会。

Abstract A closed-loop hydraulic loading and electronic data acquisition system will be acquired. The system will providethe the capability to conduct load-controlled or displacement-controlled tests on structuralmaterials and structural members under static, cyclic, or dynamic loading conditions. The dataacquisition system will be used in conjunction with the hydraulic loading system and will allowfor the simultaneous monitoring of eighty channels of data (strain, load, displacement, etc.). Theequipment requested represents a significant upgrade from the testing systems currently used bythe PIs. The current loading system is limited to static testing, and load can be applied but notcontrolled via the manual open-loop system. Current data acquisition equipment is limited inscanning speed and precision, and cannot accommodate dynamic testing.The College of Engineering is implementing a seven year strategic plan, andStructural Engineering is categorized as a thrust area on which emphasis will be placed withrespect to support and development of infrastructure. In conjunction with this plan, a new 9500square foot experimental laboratory for research and teaching in structural engineering isscheduled to open on campus in 2004. The testing system requested in this proposal wasdesigned with this in mind, as the equipment will be usable in both the existing laboratory and thenew facility. The systems designed are also easily upgradeable to accommodate long-term needs. Through a variety of mechanismsl, undergraduates will have the opportunity to use the requested equipment to conductresearch. Underrepresented groups will benefit as a result of the continued commitment the College of Engineering toward providing opportunities for these groups in engineering education.
