A new control and data acquisition system is required to preserve and upgrade our mechanical testing capabilities in the Laboratoire d'étude de la durée de vie des infrastructures publiques in the Department of Civil and Water engineering. This laboratory serves not only as the base centre of many research projects spanning from the study of cracking behaviour of ultra-high performance fibre reinforced concrete to the investigation of cyclic loading response of large-scale prefabricated aluminum bridge decks, but also as the setting for the design and development of novel methods for testing and evaluating materials. This new control and data acquisition system is urgently required to replace the current 20-year-old system, for which recent repairs have been extremely difficult to implement and replacement parts are no longer available. A breakdown of the present system would jeopardize significant portions of our research activities and would thereby impact the progress of some of our graduate students towards completion of their program. The importance of the actual control and data acquisition system cannot be understated. It is used to control and run several testing apparatuses: one 500 kN universal testing frame with t-slot testing table and a large vertical opening, one 1 MN stocky universal testing frame as well as a set of five (5) hydraulic actuators located in our large-scale environmental room. Including the hydraulic power-pack and the various manifold and valve systems, this controller and data acquisition system is at the top of a 1.5+ M$ worth of equipment used every day in research projects associated to 10 professors. The control and data acquisition system package sought are essentially three (3) components: 1) the Controller; 2) a collection of dedicated powerful interface boards; and 3) the Control Software suite. The MTS FlexTestr100 Controller is a reliable and versatile servocontroller that provides real-time reliable closed-loop control, along with a wide array of possible configurations, making it the perfect controller for our various testing set-ups. The collection of dedicated interface boards includes all the hardware needed with the controller to adequately run the hydraulic systems (frame and actuators) and capture in parallel the signals from a variety of sensors (strain, displacement, pressure, etc.). Finally, the MTS Control Software allows to create the tests and link together all of the aforementioned hardware elements. The key outcome for the users (a) a highly improved control of the test progress (essential in studies involving cracking of localized damage mechanisms); (b) an increased measurement resolution and precision, both during static and cyclic loading schemes (a necessity for some of the newest standardized test methods); and (c) a simplified and significantly upgraded capacity for developing and testing experimental procedures (a key element for optimally exploiting the testing infrastructure).

需要一个新的控制和数据采集系统，以保持和提高我们在土木工程和水利工程部出版的基础设施实验室的机械测试能力。该实验室不仅是许多研究项目的基地中心，从研究超高性能纤维混凝土的开裂行为到研究大型预制铝桥面的循环荷载响应，而且还作为设计和开发新的材料测试和评估方法的场所。迫切需要这个新的控制和数据采集系统，以取代目前已有20年历史的系统，该系统最近的维修工作极其困难，而且不再提供更换部件。现行制度的崩溃将危及我们的大部分研究活动，并因此影响我们的一些研究生完成他们的课程的进度。不能低估实际控制和数据采集系统的重要性。它用来控制和运行几个测试仪器：一个带有T型槽试验台和一个大的垂直开口的500KN万能试验架，一个1MN结实的万能试验架以及位于我们大型环境室内的一套五(5)个液压执行器。包括液压动力组件和各种歧管和阀门系统在内，这个控制器和数据采集系统是与10名教授相关的研究项目中每天使用的价值1.5多万美元的设备中的佼佼者。所寻求的控制和数据采集系统包基本上包括三(3)个组件：1)控制器；2)一组专用的功能强大的接口板；以及3)控制软件套件。MTS FlexTestr100控制器是一款可靠且多功能的伺服控制器，可提供实时可靠的闭环控制以及多种可能的配置，使其成为我们各种测试设置的完美控制器。专用接口板集合包括控制器充分运行液压系统(框架和执行器)并并行捕获来自各种传感器(应变、位移、压力等)的信号所需的所有硬件。最后，MTS控制软件允许创建测试并将上述所有硬件元素链接在一起。用户的主要成果是：(A)大大改善了对测试进度的控制(在涉及局部损伤机制破裂的研究中至关重要)；(B)在静态和循环加载方案期间提高了测量分辨率和精度(一些最新的标准化测试方法需要)；以及(C)简化和显著提高了制定和测试实验程序的能力(优化利用测试基础设施的关键要素)。
