项目摘要

This Major Research Instrumentation (MRI) project supports the acquisition of a state-of-the-art vibration measurement system to enable fundamental research and education in engineering and biology. The instrumentation will enable researchers to develop a fundamental understanding of how vibrations propagate in complex environments, leading to enhanced man-machine interfaces, more efficient renewable energy sources and new ultrasound-based therapeutic strategies. The instrumentation will catalyze interdisciplinary research collaborations among thirty faculty, staff and students and with industrial partners. The instrumentation will be integrated into coursework and labs and will enhance outreach activities for K-12 students and underrepresented minorities. These investigations will support the development of models for vibration propagation through complex systems and the development of technologies that use vibrations in novel ways. The projects will acquire high-resolution, non-contact, full-field data on structures that span size, scale, and material properties: from microscopic to larger amplitude, from short to long range, from low to high frequencies, and through varying mediums. These data will enable researchers to develop better models to understand (1) ultrasonic vibrations as it relates to surface haptic technologies; (2) vibrational communication in insects and arachnids; (3) insights into physical interactions between ultrasound and porous structures for bone healing; and (4) new designs for nature-inspired wind turbine blades.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.

该主要研究仪器（MRI）项目支持收购最先进的振动测量系统，以实现工程和生物学的基础研究和教育。该仪器将使研究人员对振动如何在复杂环境中传播有一个基本的了解，从而增强人机界面，更有效的可再生能源和新的基于超声的治疗策略。该仪器将促进30名教职员工和学生以及工业合作伙伴之间的跨学科研究合作。该仪器将被整合到课程和实验室，并将加强对K-12学生和代表性不足的少数民族的外联活动。这些研究将支持通过复杂系统的振动传播模型的开发，以及以新颖方式使用振动的技术的开发。这些项目将获得关于结构的高分辨率、非接触式、全场数据，这些数据涵盖尺寸、尺度和材料特性：从微观到较大振幅，从短到长，从低到高频率，以及通过不同的介质。这些数据将使研究人员能够开发更好的模型来理解（1）超声波振动，因为它与表面触觉技术有关;（2）昆虫和蛛形纲动物的振动通信;（3）深入了解超声波和多孔结构之间的物理相互作用，以促进骨骼愈合;（4）为自然设计新的图案-该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准。
