Embodiment Construction
[0053] The present invention proposes an observer-based detection method for track lateral irregularity, which will be further described below in conjunction with the accompanying drawings and embodiments.
[0054] The steps of the observer-based track lateral irregularity detection method are as follows:
[0055] 1. The layout of the sensing device
[0056] like figure 1 As shown, the lateral acceleration sensor Уb and the shaking head angle measuring instrument Ψb (gyroscope is enough) are installed at the center of the bogie, which are used to measure the lateral acceleration and shaking head angular velocity of the bogie during the running of the train respectively; The lateral acceleration sensor Уbd obtains the lateral acceleration of the vehicle body.
[0057] 2. Preprocessing of signal acquisition
[0058] The signal acquisition unit entity is the signal conditioning board, which mainly performs isolation processing, analog-to-digital conversion and digital filtering ...
