A non-intrusive laser doppler interferometer for measuring vibratory motion of mechanical components and a computer-based data acquisition and analysis system will be used to initiate a research laboratory at UCLA dedicated to the development of analytical and experimental techniques for the investigation of machine dynamics, and the analysis and control of noise and vibration in electro-mechanical systems. For its first application, the instrumentation will be used as part of a fully coordinated experimental and theoretical effort to study the modal and self-excited vibration phenomenon of a magnetic head suspension system in a high-performance floppy disk drive. Future applications will be related to the investigation of chatter vibration experienced in high-precision manufacturing processes.

用于测量机械部件振动运动的非侵入式激光多普勒干涉仪和基于计算机的数据采集和分析系统将用于在加州大学洛杉矶分校建立一个研究实验室，致力于开发分析和实验技术，研究机器动力学，以及分析和控制机电系统中的噪声和振动。作为其首次应用，该仪器将被用作完全协调的实验和理论工作的一部分，以研究高性能软盘驱动器中磁头悬挂系统的模式和自激振动现象。未来的应用将与高精度制造过程中经历的颤振振动的研究有关。
