摘要
本文对旋转轴扭振加速度遥测发讯头的拾振、调频及发射部分的机、电特性进行了分析,建立了理论关系模型并给出了实测结果。
In this paper, based on the research and experiment about the telemeter for measuring the torsional acceleration on revolute shafts, the characteristics of the torsional acceleration-to-frequency converter manifested by Colpitts oscillator and the transmitter are analysed. A measuring and converting model and the practical test data are also offered.
