研究了光纤布拉格传感器在感应电机机架应变监测中的应用。其基本目的是研究框架表面附连的光纤传感用于状态监测目的的可行性，即识别健康和/或故障的机器运行状态的特征。为此，报道了一项实验研究，将光纤监测的周向应变信号的频谱内容与同步监测的机架加速度和轴系扭矩信号的频谱内容进行了比较。结果表明，在光纤应变传感器监测的车架应变信号中，可以有效地识别出轴上电气不平衡和故障的特征，以及机械效应的特征。
This paper investigates the application of Fibre Bragg sensing for monitoring of induction machine frame strain. The underlying purpose is to examine the feasibility of frame surface attached fibre optic sensing to be used for condition monitoring purposes, i.e. for recognition of signatures characteristic of healthy and/or faulty machine operating conditions. To this end an experimental study is reported that compares the fibre optic monitored circumferential strain signal spectral content with that of synchronously monitored frame acceleration and shaft torque signals on a laboratory induction machine operating with and without electrical fault. It is shown that the signature of electrical unbalance and fault, as well as that of mechanical effects on the shaft can be effectively recognised in the frame strain signal monitored by the fibre optic strain sensor.
