THE MATHEMATICAL MODEL OF THE ALL-WHEEL DRIVE VEHICLE CIRCULAR MOTION IN DIFFERENT TRACTION AND ROLLING THE INNER AND OUTER WHEELS CONDITIONS, FOR A COMPARATIVE ANALYSIS OF THE VARIOUS INTERWHEEL LIMITED-SLIP DIFFERENTIALS (IW-LSD) EFFICIENCY
The mathematical model of the all-wheel drive vehicle circular motion on deformable ground surface in different conditions of traction and rolling the inner and outer wheels was developed. This work was completed with using spatial design scheme of forces and moments. The relation between slippage and slip angles of the wheels, as well as their non-linear dependence on the longitudinal and side reactions of the wheels in contact with the ground was taken into account. This model is designed for a comparative analysis of various inter-wheel limited-slip differentials (IW-LSD) efficiency. The comparative assessment of turning ability, traction reserve and efficiency of the vehicle is provided. As an indicator of the dynamic turning ability, the actual and theoretical angular velocity ratio of the vehicle’s turn is suggested.
