位标器陀螺转子动平衡测试系统设计

针对位标器陀螺转子在生产、使用过程中,由于不平衡量所带来误差、磨损等问题,本文介绍了一种基于虚拟仪器的位标器陀螺转子动平衡测试系统。当陀螺转子匀速旋转后,通过不平衡信号传感器将陀螺转子作用于机械支架的受迫振动转换成相应的不平衡信号。与此同时,基准信号传感器产生基准信号。测试系统对基准信号和不平衡信号进行采集、处理、分析和显示,根据测试所得到的结果,进行加重或者去重,达到最小可剩余不平衡量。该系统采用了基于数字相关原理的相位差测量方法,并使用LabVIEW进行软件编程。实践证明,本测试系统测试精度高,操作简单,稳定性高。

Design of gyro-rotor dynamical balance measurement system

Aiming to solve the problems of low accuracy and abrasion which are caused by the gyro-rotor imbalance,we designed a new gyro-rotor dynamical balance measurement system based on virtual instruments.When the gyro-rotor is rotating,the imbalance signal sensor acquires the imbalance signal from the mechanical bracket.Meanwhile,the reference signal sensor acquires the reference signal.After the signal processing and calculation by the VI-based system,the amount of imbalance signal will be showed on the computer...
