摘　　要：为了分析高机动性多轴车辆越障性能，建立了8×8独立悬架轮式车辆各桥车轮与地面之间接地或悬空2种情况通过台阶能力分析模型，并利用该模型结合某具体车型进行了计算分析。结果表明，在低附着系数时车辆越障高度随附着系数的增大而增大，在高附着系数时越障高度趋于定值，说明所建立的模型是合理的。To study cross - obstacle performance of a 8 × 8 wheeled vehicle with independent suspension, a method of establishing the analysis model of crossing step is investigated with taking the contact state between the wheels and ground into account . The influence of the relation between the vehicle parameters and the ground adhesion on the ability of cross - ob- stacle performance of the vehicle is obtained. When the ground adhesion is low, the obstacle height that the vehicle can be crossed increased with the accretion of the ground adhesion. When the ground adhesion is high, the obstacle height that the vehicle can be crossed closed to a fixed value with the accretion of the ground adhesion. The results show that model is reasonable.
