这一重大研究仪器(MRI)奖支持购买三维扫描激光多普勒振动仪。激光多普勒测振仪结合了一种使用相干光来测量振动物体速度的技术。该仪器将允许对高温、轻质和旋转结构的振动进行高保真测量。这将使广泛的研究项目有可能在提供可持续能源、使用轻质材料开发节油汽车和改善人类健康等领域产生重大影响。它还将加强无损检测、能源、锂离子电池监测、添加剂制造和材料科学等领域的研究。该工具将被整合到目前凯特琳大学的课程和推广计划中，例如学术兴趣Minds，这些计划针对的是代表人数较少的少数族裔和低收入学生，以培养他们对科学、技术、工程和数学学习的兴趣。该系统将被用作一个共享的研究、培训、教学和推广工具，以支持凯特琳大学以及密歇根州立大学、奥克兰大学、密歇根大学迪尔伯恩大学、密歇根大学弗林特大学和大谷州立大学等其他地区大学的跨学科努力。三维扫描激光多普勒测振仪(3D SLDV)将用于高频和高空间分辨率应用。这一能力对于以下领域的研究活动将特别关键：(1)生物医学工程，超声波治疗中的声压研究，以及皮肤和软组织表征，(2)结构健康监测和损伤检测，(3)材料建模和微结构优化，以开发具有更好振动性能的材料，(4)声塑性变形结构的微观结构表征，(5)超材料添加剂制造中的不确定性表征，(6)轮胎和接触贴片机械的动态分析，以及(7)锂离子电池监测。总而言之，3D SLDV将为凯特琳大学的研究人员和合作者提供一个强大的、非接触式的全场测量系统，该系统具有广泛的频率范围，可用于复杂结构的现场测量。该项目由主要仪器研究计划(MRI)和土木、机械和制造创新部门(CMMI)联合资助。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This Major Research Instrumentation (MRI) award supports the acquisition of a three-dimensional scanning laser Doppler vibrometer. A laser Doppler vibrometer incorporates a technique that uses coherent light to measure the velocity of vibrating objects. This instrument will allow high-fidelity measurements of vibrations for high-temperature, lightweight, and rotating structures. This will enable a breadth of research projects that have the potential to be significantly impactful in the areas of providing sustainable energy sources, using lightweight materials to develop fuel-efficient cars, and improving human health. It will also enhance research in the areas of non-destructive inspection, energy, lithium-ion battery monitoring, additive manufacturing, and material science. The instrument will be integrated into the current Kettering University curriculum and outreach programs, such as Academically Interested Minds, that target underrepresented minority and low-income students to build interest in science, technology, engineering, and math learning. The system will be used as a shared research, training, teaching and outreach tool to support interdisciplinary efforts at Kettering University as well as collaborators from other regional universities at Michigan State University, Oakland University, University of Michigan-Dearborn, University of Michigan-Flint, and Grand Valley State University.The three-dimensional scanning laser Doppler vibrometer (3D SLDV) will be used for high-frequency and high-spatial-resolution applications. This capability will be especially critical for research activities in the areas of (1) biomedical engineering, research on acoustic pressure in ultrasound therapy, and skin and soft tissue characterization, (2) structural health monitoring and damage detection, (3) material modeling and microstructure optimization to develop materials with improved vibration performance, (4) microstructural characterization of acoustoplastically deformed structures, (5) uncertainty characterization in additive manufacturing of metamaterials, (6) dynamic analysis of tires and contact patch mechanics, and (7) monitoring of Lithium-Ion batteries. Altogether, the 3D SLDV will provide researchers at Kettering University and collaborators with a robust, non-contact, full-field measurement system with a wide frequency range that can be readily used for in situ measurements of complex structures.This project is jointly funded by the Major Instrumentation Research Program (MRI) and the division of Civil, Mechanical and Manufacturing Innovation (CMMI).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
