摘要
介绍了一种应用重采样技术的旋转机械振动信号的整周期采样方法。通过三次样条插值,从定时采样的数据中获得整周期采样的数据,经过实验,证明是可行的。
This paper introduces a full period sampling method based on the resampling technology used in the sampling of rotor system vibration signals.Through thrice spline interpolation, we get full period sampling data from fix time sampling data. This method is proved feasible by an experiment.
