| 摘 要： | 针对四履带车辆特点，建立了考虑履带宽度以及滑转、滑移的四履带车辆稳态转向数学模型，并对模型进行了数值求解，分析了各因素对其稳态转向性能的影响。基于多刚体动力学软件RecurDyn对某四履带车辆进行了虚拟样机转向仿真试验，仿真结果与理论计算吻合较好，证明模型具有较高的可靠性。

| Abstract: | Based on the characteristics of four-tracked vehicles, the mathematical model of steady steering on firm ground was established, considering the crawler width and skid steering. The influences of the factors on the steering performance were analyzed. The virtual prototype of a four tracked vehicle was built based on the multi body dynamics software RecurDyn and the steering tests were completed. The virtual prototype simulation results accorded well with the numerical results, which verified the correction of the theoretical model. |
