Acquisition of a High Speed Digital Camera for Advanced Materials, Processing and Dynamic Events Research

近年来，俄克拉荷马州州立大学（OSU）在聚合物疲劳、连续薄材料（称为腹板）制造中的力学、难加工材料的高速加工、高级陶瓷的精加工以及流体-结构相互作用等领域进行了相当大的研究。它依赖于广泛的实验研究，利用先进的仪器。从这些研究中开发的技术已被转移到行业，并直接受益于赞助商和其他公司，如伊士曼柯达，3 M，Imation，宝洁，ALCOA，罗克韦尔自动化，美敦力和杜邦;研究结果已发表在领先的档案期刊和会议上。为了继续在这些领域的研究，以发现在科学和工程，并为新技术的发展转移到工业，需要一个高速数码相机系统，以调查高速力学伴随着在这些领域的研究。本提案中概述的项目需要能够现场观察这些领域中发生的高速现象。将利用该照相机进行实验，以研究未使用过的和疲劳损坏的结构聚合物中高速动态裂纹的萌生和扩展，以确定断裂的开始和模式;研究塑料和金属网的高速机械切割过程;研究先进材料的高速加工过程的机理;研究磁场辅助陶瓷抛光过程中材料去除的机理，研究薄膜（固体）和湍流空气（流体）在腹板制造过程中的相互作用，检查叶片结构响应和涡轮压缩机中的气动阻尼，高速数码相机的出现将极大地增强俄勒冈州立大学的研究基础设施，并发展EPSCoR州俄克拉荷马州的研究基础设施，以提高该州的研究竞争力;它还将帮助支持生产性研究，使美国工业不断受益，特别是网络材料行业通过网络处理研究中心，这是世界上唯一的网络处理中心，由17家美国公司赞助。

0320968Abstract There has been a considerable effort in research at Oklahoma StateUniversity (OSU) in recent years in the fields of polymer fatigue, mechanics in themanufacturing of continuous thin materials, called webs, high-speed machining ofdifficult-to-machine materials, finishing of advanced ceramics, and fluid-structureinteractions. It has relied on extensive experimental investigations utilizing advancedinstrumentation. Technologies developed from these researches have been transferredto industry and have directly benefited sponsoring and other companies, such asEastman Kodak, 3M, Imation, Procter & Gamble, ALCOA, Rockwell Automation,Medtronic, and DuPont; and research findings have been published in leading archivaljournals and conferences. To continue research in these fields for the discovery inscience and engineering and for the development of new technologies transferable toindustry, a high-speed digital camera system is needed to investigate the high-speedmechanics accompanied with the research in these areas. The projects outlined in thisproposal require the ability to observe in situ high-speed phenomena occurring in thesefields. Experiments using the camera will be conducted to investigate the dynamic crackinitiation and propagation at high-speeds in both virgin and fatigue-damaged structuralpolymers for the purpose of identifying the onset and the mode of failure; to study high-speedmechanical slitting processes of plastic and metallic webs; to study themechanisms of high-speed machining processes of advanced materials; to study themechanisms of material removal in magnetic-field-assisted ceramic polishing processes;to study the interaction of thin films (solid) and turbulent air (fluid) in web manufacturingprocesses; to examine blade structural response and aerodynamic damping inturbomachine compressors; and to study the high-speed winding of webs.The availability of high-speed digital camera will greatly enhance theresearch infrastructure at OSU, as well as develop research infrastructure in Oklahoma,an EPSCoR state, to enhance research competitiveness of the state; it will also helpsupport productive research that will continuously benefit the U.S. industry, especiallythe web material industry through the Web Handling Research Center, the only centeron web handling in the world, that is sponsored by 17 U.S. companies.
