STTR Phase II: Magneto-Rheological Fluids for Sensor Actuator Systems

这一小型企业技术转让(STTR)第二阶段项目将为各种减震应用开发先进的磁流变液。第一阶段项目的重点是微波等离子体合成技术(NANOGENTM)和化学沉淀技术；这两种技术都成功地用于合成铁、钴和氧化铁的纳米颗粒。NANOGENTM在1998年被评为100项最具创新性的技术之一，当时它获得了享有盛誉的R&D 100奖。用这些流体制备了磁流变液，初步结果发现它们的减振性能与商业上可获得的流体相当。第二阶段项目将扩大纳米粉末的生产，并对其减振特性进行测试，以帮助促进磁流变液在关键技术驱动领域的开发和应用。可能的商业应用将包括汽车悬架、混合执行器阀门、涡轮机和桥梁的半主动振动控制以及地震减振。

This Small Business Technology Transfer (STTR) Phase II project will develop advanced magnetorheological fluids for various damping applications. The Phase I project focused on a microwave plasma synthesis technique (NANOGENTM) and chemical precipitation technique; both techniques were successfully used to synthesize nanoparticles of iron, cobalt and iron oxide. NANOGENTM was selected as one of the 100 most innovative technologies in 1998 when it won the prestigious R&D 100 Award. MR fluids were prepared from these fluids and preliminary results on their damping behavior was found to be comparable with commercially available fluids. The Phase II project will scale-up the production of nanopowders and will conduct testing of their damping characteristics to help foster the development and application of MR fluids in key technology driven areas.The possible commercial applications will be in automobile suspensions, hybrid actuator valves, semi-active vibration control in turbines and bridges as well as for seismic damping.
