Abstract
结合频分复用技术与扫频光学相干测振仪，提出一种基于光学相干多点测振仪（swept-source optical coherence multi-point vibrometer, SSOCMV）的转轴轴心轨迹监测方法和系统，其具有非接触式、非侵入式、高精度以及多点振动同步测量的优点。首先，对SSOCMV的系统组成和测量原理进行了介绍与分析；其次，搭建实验对比系统以验证SSOCMV系统的测量准确性，在SSOCMV系统探头的对称位置安装电涡流传感器以同步监测转轴轴心轨迹，便于对比两个系统的测量结果。实验结果表明，基于光学相干多点测振仪的转轴轴心轨迹监系统比电涡流传感器具有更高的位移分辨率和更好的信噪比。因此，SSOCMV系统在旋转机械状态监测、参数识别和故障诊断等方面具有良好的应用前景。基于扫源光学相干多点振动仪的旋转轴中心轨迹监测方法
