PFI:BIC: The Living Bridge: The Future of Smart, User-Centered Transportation Infrastructure

新汉普郡大学的这一创新伙伴关系：建设创新能力(PFI：BIC)项目专注于一座“活的桥梁”，它体现了智能、可持续、以用户为中心的交通基础设施的未来。桥梁为社会提供了如此基本的服务，以至于它们经常被认为是理所当然的。通常情况下，只有当桥梁必须出人意料地以高昂的成本更换，或者更糟糕的是，它们失败时，才会引起公众的兴趣。Living Bridge项目将通过将地标性的纪念桥改造成研究人员、工程师、科学家和整个社区的生活实验室，创建一座自我诊断、自我报告的“智能桥梁”，动力来自当地的可再生能源潮汐能源。纪念桥是一座横跨潮汐皮斯卡塔卡河的垂直升降桥，有步行通道，连接新汉普郡的朴茨茅斯和缅因州的基特里。Living Bridge将通过在工作桥上创建孵化器平台来吸引传感器和可再生能源技术的创新者，研究人员可以从该平台上进行现场测试和评估新兴技术的影响和有效性。Living Bridge还将作为一个社区平台，教育公民了解现场和该地区发生的创新，以及如何将可再生能源纳入桥梁设计，从而产生影响远远超出该地区的可持续交通基础设施。可持续的智能桥梁是开发成功的基础设施系统的关键要素。为推动智能服务系统和清洁能源转换的发展，该项目组将设计和部署一个结构和环境监测系统，为桥梁状况评估、交通管理和环境管理提供信息；推进可再生能源技术应用；并激发公众对桥梁创新的兴趣。这个PFI：BIC项目是通过以下合作伙伴关系实现的：具有结构、机械和海洋工程、传感技术和社会科学专业知识的学术研究人员；具有仪器仪表、数据采集、潮汐能转换专业知识的小企业；以及具有桥梁设计专业知识的国家机构。Living Bridge的技术领域包括结构健康监测、采用流固耦合测量的潮汐能转换、河口环境监测和外展通信。传感器将用于校准桥梁的三维解析结构有限元模型。由该模型预测的结构响应将评估桥梁的实测结构响应是否可接受。安装在涡轮机部署平台上的仪器将测量涡轮机下游湍流流入和修正尾迹流的时空结构。得到的数据将包括涡轮机性能和载荷，用于流体-结构相互作用模型。部署的环境传感器将测量河口水质；野生动物威慑传感器将阻止鱼类进入涡轮机。水听器和摄像机将在涡轮机部署之前和期间使用，以监控由于涡轮机的存在而造成的环境变化。外展工作将通过安装在大桥上的信息亭，使公众和K-12教育工作者能够访问和理解大桥数据、历史和有关新系统的信息。公众意识将通过N.H.花岗岩州民意调查中使用的调查方法进行评估。牵头机构是新汉普郡大学(UNH)及其土木工程、机械工程和社会学系，以及海洋工程中心。主要的工业合作伙伴是一家大型企业，Macartney水下技术集团公司(德克萨斯州休斯顿)和一家小型企业Lite Enterprise，Inc.(纳舒尔，NH)。更广泛的背景合作伙伴是新汉普郡交通部、NH渔猎部门、NH港务局、NH海岸计划、朴茨茅斯市(NH)、可持续朴茨茅斯(非营利)、缅因州交通部、美国海岸警卫队、Archer/Western(马萨诸塞州坎顿市，大型企业)、Parsons-Brinkerhoff(曼彻斯特，NH，大型企业)、UNH Tech Camp、UNH基础设施和气候网络、UNH Leitzel数学、科学和工程教育中心，以及麻省理工学院改变场所(位于马萨诸塞州剑桥市的联合建筑和媒体实验室联盟)。

This Partnerships for Innovation: Building Innovation Capacity (PFI:BIC) project from the University of New Hampshire focuses on a "living bridge", which exemplifies the future of smart, sustainable, user-centered transportation infrastructure. Bridges deliver such a fundamental service to society that they are often taken for granted. Typically, bridges only stir the public's interest when they must unexpectedly be replaced at great cost, or, worse, fail. The Living Bridge project will create a self-diagnosing, self-reporting "smart bridge" powered by a local renewable energy source, tidal energy, by transforming the landmark Memorial Bridge--a vertical lift bridge over the tidal Piscataqua River, with pedestrian access connecting Portsmouth, New Hampshire to Kittery, Maine--into a living laboratory for researchers, engineers, scientists, and the community at large. The Living Bridge will engage innovators in sensor and renewable energy technology by creating an incubator platform on a working bridge, from which researchers can field test and evaluate the impact and effectiveness of emerging technologies. The Living Bridge will also serve as a community platform to educate citizens about innovations occurring at the site and in the region, and about how incorporating renewable energy into bridge design can lead to a sustainable transportation infrastructure with impact far beyond the region. Sustainable, smart bridges are key elements in developing a successful infrastructure system. To advance the state of smart service systems and clean energy conversion, this project team will design and deploy a structural and environmental monitoring system that provides information for bridge condition assessment, traffic management, and environmental stewardship; advances renewable energy technology application; and excites the general public about bridge innovations. This PFI:BIC project is enabled through partnerships between academic researchers with expertise in structural, mechanical and ocean engineering, sensing technology and social science; small businesses with expertise in instrumentation, data acquisition, tidal energy conversion; and state agencies with bridge design expertise. The Living Bridge technical areas are structural health monitoring, tidal energy conversion with fluid-structure interaction measurements, estuarine environmental monitoring, and outreach communication. Sensors will be used to calibrate a three-dimensional analytical structural finite element model of the bridge. The predicted structural response from this model will assess the measured structural response of the bridge as acceptable or not. Instruments installed on the turbine deployment platform will measure the spatio-temporal structure of the turbulent inflow and modified wake flow downstream of the turbine. Resulting data will include turbine performance and loads for use in fluid-structure interaction models. Deployed environmental sensors will measure estuarine water quality; wildlife deterrent sensors will deter fish from the turbine. Hydrophones and video cameras will be used before and during turbine deployment to monitor environmental changes due to turbine presence. Outreach efforts will make bridge data, history, and information about new systems accessible and understandable to the public and K-12 educators, facilitated by an information kiosk installed at the bridge. Public awareness will be assessed with survey methods used in the N.H. Granite State Poll. The lead institution is the University of New Hampshire (UNH) with its departments of Civil Engineering, Mechanical Engineering, and Sociology, and the Center for Ocean Engineering. Primary industrial partners are a large business, MacArtney Underwater Technology Group, Inc. (Houston, TX); and a small business, Lite Enterprises, Inc. (Nashua, NH). Broader context partners are New Hampshire Department of Transportation, NH Fish & Game Department, NH Port Authority, NH Coastal Program, City of Portsmouth (NH), Sustainable Portsmouth (nonprofit), Maine Department of Transportation, U.S. Coast Guard, Archer/Western (Canton, MA, large business), Parsons-Brinkerhoff (Manchester, NH, large business), UNH Tech Camp, UNH Infrastructure and Climate Network, UNH Leitzel Center for Mathematics, Science and Engineering Education, and Massachusetts Institute of Technology's Changing Places (a joint Architecture and Media Laboratory Consortium, in Cambridge, MA).
