本文对驱动轮沉陷量的分离、滑转沉陷影响因素和接地角的变化问题进行了研究,在此基础上提出了滑转沉陷的“滑动—旋转”机理和轮下土壤纵向稳定性的计算公式。同时研究了滑转沉陷对牵引性能的影响,建立了包括该影响在内的驱动轮牵引性能预测模型和电算程序。验证实例表明,预测值和实测值之间具有较好的一致性。
In this paper, the problem of the separation of the settlement of the driving wheel, the influencing factors of the slip settlement and the change of the grounding angle are studied. On the basis of this, the “slip-rotation” mechanism of the slip-fall and the longitudinal stability of the soil under the wheel Calculation formula. At the same time, the influence of slip subsidence on the traction performance was studied and the prediction model and calculation program of the drive wheel traction performance including the influence were established. The verification example shows that there is a good consistency between the predicted value and the measured value.
