| Abstract: | A model for road surface roughness recognition was established based on dynamic response of tracked vehicle body. NARX neural network structure was adopted in the model, and dynamic response signals of tracked vehicle body were taken as inputs and road surface roughness values were taken as outputs. Correlation coefficient, root mean square error, and absolute error cumulative probability density were proposed as indexes of recognition effectiveness evaluation, and the fusion method of the three indexes was proposed. Based on orthogonal experimental design, the balance between the number of input and the recognition effectiveness of road roughness recognition model was analyzed and realized, which simplified the layout of the sensor test system. The recognition effectiveness of road roughness under different road surfaces, different sampling frequencyies, and different speeds was analyzed. The results show that the proposed model may satisfy the practical engineering needs. |
