Abstract0529440Faramarz GordaninejaUniv Nevada/RenoThis project investigates a novel magneto-rheological elastomer (MRE) material system that is a sensor, an actuator, and a tunable shock and vibration absorber (TSVA) at the same time. MREs can function not only in high frequencies (kilohertz) and go through large deformations, but can also provide field-controllable storage and damping characteristics. Theoretical and experimental studies will ba carried out to establish a fundamental understanding of the behavior of a new class of MREs with superior characteristics over the state-of-the-art materials. Novel surface treated magnetic particles will be utilized. New MREs will be synthesized with various blends of thermoset and thermoplastic elastomers and synthetic rubber with various particle sizes in random or field-oriented arrangements. One very useful and practical application of MREs is to utilize them as harmonic TSVA/sensor devices to sense and isolate vibration in counter unbalanced rotating shafts. MREs could be utilized for health monitoring and civil infrastructure protection exposed to natural hazards.The broader impacts include establishing an infrastructure in MREs research in Nevada, a collaboration between mechanical and chemical engineering departments and industry, educating graduate and undergraduate students in this multidisciplinary area, and attracting high school students to summer training at the University through various demonstrations of the technology on and off the campus. This is a GOALI project supported under sensor initiative NSF 05-526.

摘要0529440 Faramarz Gordanineja内华达州/里诺该项目研究了一种新型的磁流变弹性体（MRE）材料系统，该系统同时是传感器、致动器和可调冲击和振动吸收器（TSVA）。 MRE不仅可以在高频（千赫兹）下工作并经历大的变形，而且还可以提供场可控的存储和阻尼特性。将进行理论和实验研究，以建立对一类新的MRE的行为的基本理解，该MRE具有比最先进的材料更优越的上级特性。 将使用新型表面处理的磁性颗粒。 新的MRE将与热固性和热塑性弹性体的各种共混物和合成橡胶以随机或场定向排列的各种粒度合成。 磁流变阻尼器的一个非常有用和实际的应用是利用它们作为谐波TSVA/传感器装置来感测和隔离不平衡旋转轴中的振动。MRE可用于健康监测和暴露于自然灾害的民用基础设施保护。更广泛的影响包括在内华达州建立MRE研究的基础设施，机械和化学工程部门与工业之间的合作，在这个多学科领域教育研究生和本科生，并通过校园内外的各种技术演示吸引高中生参加大学的暑期培训。 这是在传感器倡议NSF 05-526下支持的GOALI项目。
