| 摘 要： | 为了分析2自由度铰接轮式车辆的越障能力,通过简化其越障时的力学模型分别给出了前轮同时越障和单侧轮越障的平衡方程。由于在复杂非结构环境下,诸如附着系数、滚动阻力系数等这些对车辆越障起到关键作用的地面参数具有不确定性,从而导致了顺利通过障碍所用的牵引力也是不确定的。文中用区间表示这些不确定参数,通过区间分析得到了该铰接车顺...

| Abstract: | In order to analyze the obstacle surmounting capability of a wheeled vehicle with a 2-DoF articulated frame,the equilibrium equations under the simultaneously surmounting the obstacle by 2 front wheels and surmounting the obstacle by a single front wheel were derived using a simplified obstacle surmounting mechanical model.As in rough-terrain unstructured environment,the key terrain parameters,such as the adhesion coefficient,the rolling resistance coefficient,etc.,are uncertain,the traction force to surmou... |
