振动校准中的激励控制

The Excitation Control in Vibration Calibration

本文以振动校准中的FFT技术为背景,对正弦、随机和脉冲激励技术的优缺点进行了综合分析,给出了激振形式的选用原则及其参数控制方法,并通过典型传感器的振动校准对以上结论进行了验证。

In this paper,the principle by which the excitation mode is chosen and methods for excitation parameters control are put forward through analysis of advantages and disadvantages of various kinds of excitation,such as sinusoidal,random and impulse.The principle and methods are verified by the vibration calibration of typical transducers.
