为了预测轮式车辆垂直障碍通过能力并获取通过障碍过程中传动系的准确载荷，建立了用于越障过程分析的统一模型，模型统一描述了任意轴数车辆的任意轴的越障过程，综合考虑了越障过程中越障轮与非越障轮附着系数差异及悬架限位、车轮离地等影响因素。讨论了障碍通过能力判定指标，验证了传动系载荷计算的准确性，分析了悬架限位行程对传动系载荷的影响。

To predict vertical step passability of wheeled vehicle and get driveline torque,this paper presented a unified obstacle crossing model.The model could simulate climbing process of any given axle of a vehicle with any axles.Factors such as adhesion coefficient difference between climbing wheel and rolling wheel,suspension bound and rebound limits,wheel liftoff were considered.Passability cri-teria of simulation results was discussed.The model was validated through tests.Influence of suspen-sion bound limits on driveline torque was analyzed.
