“…When a tire is subjected to static loads, its convex tread arc and large sidewall deformation lead to maximum stress distribution on the central rib [21][22][23][24]. Since the tread is a rubber extrusion, longitudinal and transverse stresses in the tire are generated in the contact area.…”

Modal parameter model acts as an analytical model of tire, because it can represent the entire tire characteristics, when applied to the tire modelling. However, without considering the effect of transfer characteristics of adjacent tread spring elements, the accuracy of modal parameter model may be limited in previous studies. Based on contact mechanics and the modal parameter model, a novel tread model is proposed considering tread transfer characteristics, and then a modified model using the modal parameters was obtained using the novel tread model. The effects of tire external characteristics were analyzed by modifying the modal parameter static vertical model. Finally, the experimental and calculated data were compared, the proposed tread model improved the accuracy of calculation. The results show that the tread transfer characteristics significantly affect contact length, i.e., by improving the predictive accuracy by 50 %, and the effect on improving the squat of tire can be ignored. The developed model may help to optimize tire modelling.

“…The analysis revealed that one way to pit trucks efficiency upgrading in open pits tight working space is the trucks maneuvering abilities improvement [9]. At AC electric traction drive the automatic control system allows to control the motor's rotation forcibly and individually for the rear wheel of starboard and port side if it's necessary to rim pulls difference increasing, which provides additional yaw moment also creating the so-called phenomenon of "additional forced turn" as the vehicle maneuver benefit.…”

The study is dedicated to increasing open pit trucks with electrical transmission maneuverability indices. The possibility of forced controllability usage of rear traction wheels of open pit truck with the electrical transmission, which enables them to carry out maneuvers with the usage of a forced additional turn is presented. For the first time, there has been worked out a mathematical model of the forced additional turn. It enables to determine a correlation of rotational speed ratio of rear traction wheels of starboard and port sides of the wheeled vehicle relative to a tire-to-surface friction coefficient. Firstly, the analytical dependences, which allow predicting the indices of open pit trucks maneuverability while using the forced additional turn are determined. The mathematical model adopted to appropriate truck's electric drive control algorithm can lead to trucks performance increasing by means of maneuvering time reducing.

“…is study was meaningful in terms of research aspect. e three-dimensional stress distribution of heavy-duty truck tires under various rolling conditions was obtained, and it pointed out that the critical slip ratio was around 18%, the braking force reached its maximum [10], whereas the critical slip rates for acceleration and braking state were not compared. A widebase tire was modeled by Hernandez and Al-Qadi [11] to predict contact stress.…”

e contact stress distribution of tire-pavement is generally assumed to be uniformly distributed in circles or rectangles in the pavement design. is simplification can solve some common engineering problems, but it neglects two factors including magnitude and direction of the contact stress. e main purpose of this paper is to analyze the contact stress distribution between the bus tire and the pavement under different driving conditions and pinpoint and compare the critical slip ratio during braking and acceleration. First, a tire-pavement simulated contact model is constructed by ABAQUS. Next, we compare, respectively, contact stresses in the vertical, longitudinal, and transverse directions at various rolling conditions and analyze the longitudinal forces at different slip ratios during braking and acceleration. It is observed that the magnitude, direction, and nonuniform distribution of contact stress are affected by the multiple working conditions while the bus is working. Meanwhile, in the braking and acceleration conditions, the longitudinal force grows rapidly as the slip ratio increases, and then grows slowly and at last decreases when the critical slip ratio is reached. However, the critical slip ratio at the time of braking differs from that at the time of acceleration, and the former is smaller than the latter.
