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).

需要一种新的控制和数据采集系统，以保持和提高我们在土木和水工程部内公共基础设施的<s:1> <s:1> <s:1> <s:1> <s:1> <s:1> <s:1> <s:1>)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础中心，从超高性能纤维增强混凝土的开裂行为研究到大型预制铝桥面的循环加载响应研究，而且还作为设计和开发测试和评估材料的新方法的场所。迫切需要这种新的控制和数据采集系统来取代目前已有20年历史的系统，该系统最近的维修工作极其困难，而且更换部件也不再可用。当前系统的崩溃将危及我们研究活动的重要部分，从而影响我们的一些研究生完成他们的项目的进展。实际控制和数据采集系统的重要性不容低估。用于控制和运行几台试验设备：位于我们大型环境室内的一台500 kN带t槽试验台和大垂直开口的万能试验架，一台1 MN结实的万能试验架和一组5个液压执行器。包括液压动力包、各种歧管和阀门系统在内，该控制器和数据采集系统是10名教授每天在研究项目中使用的价值150多万美元的设备中的顶级设备。所寻求的控制和数据采集系统包本质上有三(3)个组成部分：1)控制器；2)一组专用功能强大的接口板；3)控制软件套件。MTS FlexTestr100控制器是一款可靠的多功能伺服控制器，提供实时可靠的闭环控制，以及各种可能的配置，使其成为我们各种测试设置的完美控制器。专用接口板的集合包括控制器所需的所有硬件，以充分运行液压系统（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。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。用户的关键结果(a)对测试进度的高度改进控制（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中增加测量分辨率和精度（一些最新的标准化测试方法的必要条件）；(c)开发和测试实验程序的简化和显著升级的能力（优化利用测试基础设施的关键要素）。
