AB - In the cable force detection of the cable bridge, the frequency method is the most suitable and most commonly used method. And in the application of the frequency method, the core issue is the pickup of the natural frequency. In the practice of the general frequency method, the natural frequency is often picked up by collecting the vibration response signal of the bridge cable, and then analyzing the spectrum to pick up the natural frequency. This method can be applied to most cables. However, for some cables with unsatisfactory acquisition signals, the periodicity of the signal on the spectrogram will not be obvious. At this time, further cepstrum analysis of the cable signal can better analyze the spectral period of the cable vibration response signal in order to obtain a more accurate natural frequency and calculate a more accurate cable force value.
