摘要：基于8×8越野车独立悬架匹配计算，各种参数的设定均为理想状态，整车质心为在数模中计算所得，弹簧刚度取满载时的刚度，忽略越障过程中的刚度变化，且整车轴荷为估算值。通过设定不同地面摩擦系数的情况下，建立数学模型，计算四个轴越障高度以及各轴所需驱动力。该计算方法也适用于轻、中型越野车越障能力计算。

Abstract：Matching calculation is based on 8×8 independent suspension off-road vehicles, Set various parameters are ideal state，The vehicle centroid is calculated with Modulus, Stiffness of the spring stiffness to take full load, ignoring the change of the stiffness in the process of over obstacle, and the vehicle axle load for the estimates. By setting the case where different ground friction coefficient, Mathematical model, Calculation of the four axes obstacle height and the driving force required for each axis. This calculation method is also suitable for light and medium-sized sport utility vehicle climbing obstacle capability calculations.
Key words：obstacle height；the driving force；computational methods；vehicle mobility
