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

摘要近年来，俄克拉何马州立大学（OSU）在聚合物疲劳、连续薄材料（称为网）制造中的力学、难加工材料的高速加工、高级陶瓷的精加工和流固耦合等领域进行了大量的研究。它依赖于使用先进仪器的广泛实验研究。从这些研究中开发的技术已经转移到工业中，并直接使赞助商和其他公司受益，如伊士曼柯达，3M, Imation，宝洁，美国铝业，罗克韦尔自动化，美敦力和杜邦；研究成果已在主要档案期刊和会议上发表。为了继续在这些领域的研究，以发现科学和工程以及开发可转移的新技术，需要高速数码相机系统来研究伴随这些领域研究的高速力学。本提案中概述的项目要求能够观察这些领域中发生的现场高速现象。为了确定失效的开始和模式，将使用相机进行实验，以研究未加工和疲劳损伤结构聚合物的高速动态裂纹萌生和扩展；研究了塑料和金属腹板的高速机械分切工艺；研究先进材料的高速加工机理；研究磁场辅助陶瓷抛光过程中材料去除的机理；研究卷材制造过程中薄膜（固体）与湍流空气（流体）的相互作用；对涡轮压气机叶片结构响应和气动阻尼进行了研究。并研究蛛网的高速缠绕。高速数码相机的可用性将极大地增强俄勒冈州立大学的研究基础设施，并在EPSCoR州俄克拉荷马州发展研究基础设施，以提高该州的研究竞争力；它还将帮助支持富有成效的研究，这些研究将持续造福美国工业，特别是通过网络处理研究中心，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.
