Instrumentation Laboratory for Machinery Diagnostics and Condition Monitoring for Engineering Technology Program

该项目开发了一个用于机械诊断和状态监测的仪器实验室，以满足传授与机械部件早期故障的动态表征、检测和预测相关的动手技能的需要。阐述了振动信号的共振和非共振响应、傅里叶谱、传递函数、相干和级联等诊断学概念，并介绍了用于快速数据采集和分析的传感器及其计算机接口的选择。用于机器诊断的仪器应用程序是该项目的核心。该实验室能够为德克萨斯农工大学四年制工程技术专业的高年级本科生提供连贯有效的基本振动原理及其在机械诊断中的应用方面的指导。该实验室用于三门相关的课程，即应用振动学、仪器仪表和机电系统。每年将有近150名机械、制造和电子工程技术专业的学生受益。

This project develops an instrumentation laboratory for machinery diagnostics and condition monitoring to meet the need for imparting hands-on, technical skills related to the dynamic characterization, detection and prediction of incipient failures of machine components. Diagnostics concepts such as resonant and off-resonant response, Fourier spectrum, transfer function, coherence and cascading of vibration signals are demonstrated, as well as introduction to the selection of transducers and their computer interface for rapid data acquisition and analysis. Instrumentation applications for machine diagnostics is central to this project. The laboratory enables cohesive and effective instruction of basic vibration principles and their application for machine diagnosis, to the four year upper level undergraduate engineering technology students of Texas A&M University. The laboratory is used in three interrelated courses, namely Applied Vibrations, Instrumentation, and Electro-Mechanical Systems. Nearly 150 students annually from the mechanical, manufacturing and electronics engineering technology specialties will benefit.
