摘要
针对工程领域(超)低频的振动问题,介绍了一种基于无源伺服传感器的振动测量系统。阐述了系统的特点和组成,着重分析了无源伺服反馈传感器的特点和原理,构建了传感器的数学模型,并比较了反馈前后传感器性能的差异,分析了反馈后传感器的基本参数。给出了部分测试数据和应用实例,分析了系统的抗干扰问题。最后,给出了一些结论。
The characteristics and forming of a vibration-measuring system were introduced. The vibration-measuring system was composed of passive servo vibration pickups. The nature of feedback and the principle with which the passive servo vibration pickup worked were analyzed. The characteristics of the system before and after feedback were compared. Some test data and examples of application were given. The anti-jamming problem of the vibration-measuring system was analyzed also. Finally, some useful conclusions were obtained.
