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）项目支持获得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波的治疗策略。该仪器将促进30名教职员工和学生之间以及与工业合作伙伴之间的跨学科研究合作。该仪器将整合到课程作业和实验室中，并将加强K-12学生和代表性不足的少数民族的外展活动。这些研究将支持复杂系统中振动传播模型的发展，以及以新方式使用振动的技术的发展。这些项目将获取高分辨率、非接触式、关于结构大小、规模和材料特性的全场数据：从微观到较大振幅，从短距离到长距离，从低频到高频，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)与表面触觉技术相关的超声波振动；(2)昆虫和蛛形纲动物的振动交流；(3)超声与多孔结构在骨愈合中的物理相互作用；(4)以自然为灵感的风力涡轮机叶片的新设计。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
