A Design of Vibration Acceleration Signal Integrator Based on LabVIEW

Under the condition of vibration acceleration sensor only, if vibration speed or vibration displacement signal is to be obtained, the vibration acceleration signal must be integrated by hardware or software. In order to solve these problems, an FFT signal integrator based on the virtual instrument of Labview is designed. Through the simulation of the input analog vibration acceleration signal, the integration result of the integrator is compared with the theoretical value, which proves that the signal integrator is very reliable. The application of the integrator can reduce the input of hardware and save the cost.
