Proposal ID: 0409557PI: Boedo, StephenOrganization: Rochester Institute of TechnologyTitle: Wear investigation of compliant microbearing systemsThis project pertains to the fabrication and testing of novel compliant microbearing systems as a means of alleviating stiction, seizure, and high wear observed in current rotating micromachinery components. The primary focus of the project is to exploit structural compliance to enhance microbearing system performance, with surface coatings being a secondary concern. This project is expected to form a framework to lead researchers into combining more complex bearing structures with particular surface coatings. The proposed test bearing is comprised of a free rotor with compliant surfaces that rotates about a fixed, rigid hub through the action of an external air jet. Computational studies have indicated that a rotor comprised of a compliant bearing surface has substantially higher load capacity than that obtained with a conventional rigid rotor. Particular emphasis of the project is to develop a reliable and repeatable fabrication method and test protocol to understand the effects of elasticity, surface roughness, load, and speed on microbearing surface wear. The intellectual merit of the project will lead to the development of reliable MEMS-based microturbine, micropump, and microactuator components that can be readily integrated into larger micropower and lab-on-chip systems. The broader impact of the project will be accomplished through tribology-based laboratory sessions aimed at under-represented groups in the Rochester area, along with integration of research results into a multidisciplinary and graduate microsystems curriculum being developed at RIT.

提案ID: 0409557PI: Boedo， stephen组织：罗切斯特理工学院标题：柔性微轴承系统的磨损调查该项目涉及新型柔性微轴承系统的制造和测试，作为减轻当前旋转微机械部件中观察到的僵硬，痉挛和高磨损的手段。该项目的主要重点是利用结构顺应性来提高微轴承系统的性能，其次是表面涂层。该项目有望形成一个框架，引导研究人员将更复杂的轴承结构与特定的表面涂层结合起来。所提出的测试轴承由一个自由转子组成，该转子具有柔顺的表面，通过外部空气射流的作用围绕固定的刚性轮毂旋转。计算研究表明，由柔性支承面组成的转子具有比传统刚性转子高得多的承载能力。该项目的重点是开发一种可靠的、可重复的制造方法和测试方案，以了解弹性、表面粗糙度、载荷和速度对微轴承表面磨损的影响。该项目的智力优势将导致可靠的基于mems的微涡轮、微泵和微致动器组件的开发，这些组件可以很容易地集成到更大的微功率和芯片实验室系统中。该项目的广泛影响将通过针对罗切斯特地区代表性不足的群体的摩擦学基础实验室会议来完成，同时将研究成果整合到RIT正在开发的多学科和研究生微系统课程中。
