Enigneering Research Equipment Grant: Vibration Isolation Table Power Amplifiers Microprocessors

该项目为采购支持机电设备研究和接触物理研究的设备提供资源。该设备包括隔振台、功率放大器和信号处理计算机。两个研究项目将从设备的可用性中受益。第一个是关于支持超精密系统(激光安装、精密加工系统、导航陀螺仪等)的结构的振动控制方法的开发。隔振台为与该项目相关的超精密实验提供了一个静止的环境。该方法利用了铁和稀土金属材料的磁致伸缩特性。第二个项目侧重于了解热弹性不稳定性的摩擦学现象，即电机电刷和转子之间的滑动接触发生在电刷表面的微观表面凸起(热丘)上。投手丘倾向于以一种未知的模式在刷子面上移动。这项研究旨在预测这个热丘的运动。该设备还将用于强调电接触的一般摩擦学研究。

This project provides resources to procure equipment to support electromechanical devices research and contact physics research. The equipment comprises a vibration isolation table, power amplifiers and a signal processing computer. Two research projects will benefit from the availability of the equipment. The first is concerned with the development of a vibration control method for structures which support ultra precise systems (laser mounts, precise machining systems, navigational gyroscopes, etc). The vibration isolation table provides a quiescent environment for ultra precise experiments associated with this project. The method takes advantage of the magnetostrictive properties of materials made of iron and rare earth metals. The second project focuses on understanding the tribological phenomenon of thermoelastic instability, whereby sliding contact between a motor brush and rotor occurs over microscopic surface bumps (thermal mounds) on the brush face. The mound tends to move over the brush face in an unknown pattern. The research is directed at predicting this thermal mound motion. The equipment will also be used for general tribology research which emphasizes electrical contacts.
