项目摘要

The overarching aim is to develop a facility for the testing and evaluating of large structures, called Structure 2025. To construct such a facility it is necessary to purchase specialist equipment, which comprises imaging, loading and control systems. Structures 2025 will provide a novel integrated imaging and loading system that is flexible, and can be used for the testing and assessment of a wide range of structures across industry sectors. The unique feature of Structures 2025 is that it will, for the first time, enable data-rich studies of the behaviour of large components and structures subjected to realistic loading scenarios mimicking the behaviour of a structure in service. It will be possible to model the loads felt by aircraft in flight, railway structures, bridges and cars and understand better how the structure supports the load experienced in service. Structures 2025 will enable the introduction of new lightweight materials into transport systems allowing energy savings and a more sustainable approach to design. The uniqueness of Structures 2025 is predicated on imaging, where large amounts of data can be collected to provide information about the structural response. The imaging will be based on both visible light and infra-red camera systems which capture data from the loaded structure and used to evaluate strains and deformations. Traditional sensors take only point readings, whereas images provide data over a wide field of view, since each sensor in the imaging device provides a measurement, the terminology 'data-rich' is applied. A complete system integration will be developed and implemented, that combines the load application using a multi-actuator loading system with the imaging systems. The combination of techniques into a single integrated system will be unique internationally, and will enable the accurate assessment of the interactions between material failure mechanisms/modes and structural stiffness/strength driven failure modes on a hitherto unattainable level of physical realism. Structures 2025 will provide what can be termed high-fidelity data-rich testing of structural components, to integrate with multi-scale computational modelling to provide better predicitive models of structural failure and create safer and more efficient structures. Structures 2025 will be developed in close collaboration with 16 industry partners, representing the rail infrastructure, civil engineering, experimental technique development, energy systems, marine and offshore, and aerospace sectors, as well as several university partners.

总体目标是开发一种用于测试和评估大型结构的设备，名为Structure 2025。为了建造这样的设施，需要购买专门的设备，其中包括成像、装载和控制系统。Structures 2025将提供一种灵活的新型集成成像和加载系统，可用于跨行业的各种结构的测试和评估。结构2025的独特特征在于，它将首次实现对大部件和结构的行为的数据丰富的研究，所述大部件和结构受到模拟在役结构的行为的真实加载场景的影响。这将有可能对飞机在飞行中感受到的载荷、铁路结构、桥梁和汽车进行建模，并更好地了解结构如何支撑服务中经历的载荷。结构2025将能够将新的轻质材料引入交通系统，从而实现节能和更可持续的设计方法。结构2025的唯一性基于成像，其中可以收集大量数据以提供关于结构响应的信息。成像将基于可见光和红外线相机系统，这些系统从加载的结构中捕获数据，并用于评估应变和变形。传统的传感器只获取点读数，而图像提供大范围的数据，因为成像设备中的每个传感器都提供测量，所以应用了术语“丰富的数据”。将开发和实施完整的系统集成，将使用多执行器加载系统的加载应用与成像系统相结合。将技术组合成一个单一的集成系统将是国际上独一无二的，并将能够在迄今无法达到的物理现实主义水平上准确评估材料失效机制/模式与结构刚度/强度驱动的失效模式之间的相互作用。Structures 2025将提供可称为高保真的、数据丰富的结构部件测试，与多尺度计算建模相结合，以提供更好的结构失效预测模型，并创建更安全和更高效的结构。结构2025将与16个行业合作伙伴密切合作开发，这些合作伙伴代表铁路基础设施、土木工程、实验技术开发、能源系统、海洋和海上以及航空航天部门，以及几个大学合作伙伴。
