Abstract
On the base of analysis on the working state of wheels during skid steering of wheeled vehicles with consideration of the lateral nonlinear slip and uneven load distribution of tire, a turning resistance coefficient model for skid-steer wheeled vehicle is established with reference to the steering theory of tracked vehicles. Through real-time collection of the oil pressure data of steering mechanism, the turning resistance coefficients under different turning radius are indirectly measured. The results show that the accuracy of turning resistance coefficient model is acceptable, and the turning resistance coefficient of skid steer wheeled vehicles is smaller than that of tracked vehicles.
