Abstract: The pivot steering resistance torque of heavy vehicle is one of the key parameters that affect the design and control performance of its steering system. Accurate and reliable resistance torque model can improve the design level, stability and control ability of the steering drive system, and has an important effect on it. In order to establish a resistance torque model that can accurately reproduce actual steering conditions, the elastic hysteresis friction force generated by the deformation of the tread unit when the tire turns is combined with the Maxwell hysteresis model. The pivot steering resistance torque model considering tire hysteresis behavior is proposed, which can effectively predict the resistance torque when tires are changed arbitrarily. The influence of steering frequency, steering angle amplitude and vertical load on resistance torque is explored based on the heavy-duty vehicle single-axle steering system test bench. The system steering angle input is designed based on typical hysteresis behavior, the reproducibility and actual hysteresis behavior of the pivot steering resistance torque model for erasure characteristics, multi-value characteristics, congruence characteristics, and return point memory is clarified. The results showed that this model can reproduce the typical hysteresis behavior of erasing characteristics, congruential characteristics and multi-value characteristics, which is consistent with the standard hysteresis system and has universality. However, the steering resistance torque of heavy vehicles has particularity in the memory characteristics of the return point, it only shows good memory characteristics of the return point when the tire rotation angle is greater than the accumulating angle. In summary, it can provide a valuable model reference for the research on the pivot steering resistance torque model of heavy vehicle.
