Vibration acceleration signal processing method MA
4.0
The displacement measurement method of acceleration signal based on numerical integration belongs to the field of signal processing. Firstly, the discrete acceleration signal is numerically integrated, and then the integrated signal is modified by envelope method. After twice integration and twice envelope correction, the displacement signal can be obtained. The envelope method is used to modify the velocity and displacement signals after integration, which can eliminate the trend term produced in the integration process and suppress the interference of noise, and then obtain the effective displacement signal.
