| 摘 要： | 大型高速旋转机械是电力、能源、化工、航空和船舶等行业的关键设备,其稳定运行是安全、高效生产的决定性因素.为了监控或检测这类机械的运行参数,确定其整体或局部的性能是否正常,设计了用于高速旋转机械径向振动检测的反射式光强调制型非接触式光纤传感系统,对检测系统的工作原理做了详细介绍.对半导体激光器恒稳控制系统和激光光纤耦合系统进行了研究,并给出了相应的系统设计.设计了新型的光纤测头,提出了相应的补偿方案,并对其输出特性进行了详细的分析.研究结果表明,该测试系统能有效地消除因光源光强波动、光纤弯曲损耗、表面反射率等因素对输出特性的影响,可以在电磁干扰严重和高温等恶劣环境下实现对高速旋转机械径向振动的检测. |
