Transverse acceleration data processing method and device for abnormal vehicle body in turnout section

The invention discloses a turnout section abnormal vehicle body transverse acceleration data processing method and device. The method comprises the steps that the running speed of a vehicle body passing through a turnout section, transverse acceleration waveform data, the curvature of the portion, making contact with a wheel pair of the vehicle body, of the turnout section and the curve outer rail superelevation are obtained; determining the offset degree of the transverse acceleration waveform data; whether the transverse acceleration waveform data is abnormal or not is judged according to the running speed of the vehicle body passing through the turnout section, the curvature of the portion, making contact with a wheel pair of the vehicle body, of the turnout section, the curve outer rail superelevation, the deviation degree and a preset deviation degree threshold value; when the transverse acceleration waveform data is abnormal, correcting the abnormal transverse acceleration waveform data according to the
