本文提出一种校准压电加速度计共振频率及阻尼常数的电流冲击法,它是利用压电传感器为双向传感器这一特点来实现的。此法具有如下优点:以电流为冲击信号,其大小及波形易于控制;可在实际应用条件下进行校准;可用通用示波器观察在δ(t)电流信号冲击下、压电加速度计输出电压信号的整个过渡过程。 In this paper, a current impulse method is proposed to calibrate the resonant frequency and damping constant of a piezoelectric accelerometer, which is achieved by using the piezoelectric sensor as a bidirectional sensor. This method has the following advantages: the current as the impact of the signal, the size and waveform easy to control; can be calibrated under practical application; can be observed with a common oscilloscope in the δ (t) current signal impact, the piezoelectric accelerometer output voltage signal The entire transition process.
