Acquisition of Equipment and Instrumentation for Blast Mitigation Research

摘要本主要研究仪器（MRI）项目的目的是为目前正在建设中的爆炸加载实验室（ELL）采购专门的仪器和设备。ELL将允许在受控环境中对建筑物和桥梁等关键基础设施的结构部件、组件和系统进行独一无二的实时爆炸和冲击测试。该测试实验室是世界上第一个能够在不产生实际爆炸的情况下，准确、反复地进行模拟爆炸载荷测试，并表征其对结构的影响，用于开发改造和硬化优化技术的设施。在ELL对结构系统或组件进行大型或全尺寸测试期间，将在特定位置分布大量传感器，以便获得精确的测量结果，以研究非线性失效机制的发展。开发ELL的一个重要因素是采购强大的、最先进的仪器和传感器，这些仪器和传感器可以在室外环境中运行，数据采集系统和高性能网络功能。关键部件有：实时分布式数据采集系统、高速数码相机、相机测量系统、一系列传统传感器如dcdt。其愿景是为ELL提供足够的仪器，可用于使用基于互联网的技术将最先进的爆炸工程实验和计算研究整合到教育课程中。ELL所需的设备可以用来促进加州大学圣地亚哥分校斯克里普斯海洋学研究所（SIO）的研究，进一步开发ROADNet，这是一个网络和信息管理系统，可以实时向各种最终用户提供数据。最先进的ELL设施将为美国现有的测试设施增加一个重要的新维度和能力，并促进结构工程、动力系统和控制以及信息技术的研究。

AbstractThe objective of this Major Research Instrumentation (MRI) project is to procure instrumentation and equipment specifically for an Explosive Loading Laboratory (ELL), which is currently under construction. The ELL will allow for one-of-a-kind real time blast and impact testing of structural components, assemblies, and systems of critical infrastructure such as buildings and bridges in a controlled environment. The testing laboratory is the first facility in the world that can accurately and repeatedly performs simulated explosive loading tests and characterize their effects on structures for use in developing retrofit and hardening optimization technologies without creating actual explosions.During large- or full-scale testing of structural systems or assemblies at the ELL, a large array of sensors will be distributed in specific locations such that precise measurements can be obtained to investigate the development of non-linear failure mechanisms. A vital element in the development of the ELL is the procurement of robust, state-of- the-art instrumentation and sensors that can be operated in an outdoor environment, data acquisition systems and high performance networking capabilities. The key components are: real-time distributed data-acquisition systems, a high-speed digital camera, camera measurement systems, a range of conventional sensors such as DCDTs. The vision is to provide the ELL with sufficient instrumentation that can be used to integrate state-of-the-art blast engineering experimental and computational research into educational curriculum using internet-based technologies. The equipment requested for the ELL can be leveraged to promote research being conducted at the Scripps Institute of Oceanography (SIO) at UCSD, for further development of ROADNet, a network and information management system that will deliver data to a variety of end users in real-time. The state-of-the-art ELL facility, will add a significant new dimension and capabilities to existing United States testing facilities and promote research in Structural Engineering, Dynamic Systems and Control, and Information Technology.
