| 摘 要： | 冲击响应法简单易行，在传感器动态标定中常被采用．但其激励信号一冲击力的时间间隔和幅度对实验结果影响较大，本文从实验和理论两方面对此进行探讨．激励信号的频率范国必须覆盖传感器的工作频带，其幅值应使传感器工作在线性区．要得到可靠的频率响应函数的估值，应选择合适的激励信号．

| Abstract: | The shock response method is often adopted in the dynamic calibrations of sensor because it is easy and simple.But the duration and amplitude of impulsing signal (shock force)have great effects on the experimental.results.This paper deals with the problem by the experimental and theoretical methods.The frequency range of impulsing signal must cover the working frequency hand of sensor, and its amplitude must have sensor worked in the linear region.A suitable impulsing Shoal is chosen to obtain the reliable estimated value of frequency response function. |
