vehicle trafficability slip sinkage effect Gauss-Newton algorithm real vehicle test wheel force transducer
To improve the semi-empirical model, the slip sinkage effect is analyzed based on the real vehicle test. A dynamic testing system is used to gain the dynamic responses of wheel-soil interactions. The Gauss-Newton algorithm is adopted to estimate the undetermined parameters involved in the slip sinkage models. Wong’s original model is compared with three typical slip sinkage models on the prediction performance of a drawbar pull. The maximum error rate, root mean squared error and correlation coefficient are utilized to evaluate the performance. The results indicate that the slip sinkage models outperform Wong’s model and greatly improve the prediction accuracy. Lyasko’s model is confirmed as an outstanding one for its comprehensive performance. Hence, the existence of the slip sinkage effect is validated. Lyasko’s model is selected as an optimal one for the practical evaluation of military vehicle trafficability.
