A New Method of Eliminating Outliers in Data Processing of Tracked Vehicle Vibration Signal
The existence of outliers can produce false harmonic frequency components in data processing for vibration signal of tracked vehicle.The paper uses the Wright standards to judge details coefficients of outliers and calculates new details coefficients to replace the ones of the outliers by weighted coefficient method.The signal can be reconstructed with new details coefficients .The results show that the new method can retain the maximum information of singal after eliminating the outliers , meet the data distribution and reduce variance.
