摘　　要：为了在总体设计阶段对高机动军用越野汽车的最大爬坡度进行合理计算,从汽车纵向动力学平衡方程入手,针对车型最大爬坡度较大的特点,分析了平衡方程成立的隐含条件,给出了基于驱动力的最大爬坡度计算方法;在此基础上,基于附着条件,对四轮锁止情况下最大爬坡度的计算进行了探讨,从而得到了高机动越野汽车最大爬坡度的完整计算方法。实例计算表明,给出的方法实用可行;同时发现,提高最大爬坡度除了采取提高发动机的输出转矩和传动比外,还应注意整车布置,充分利用地面附着系数。In order to predict the maximum gradeability of military of high mobility vehicle at the beginning of designation, the balance equation along the driving direction was analyzed. The implicit condition of the balance equation was concluded for high I^adeability. Then the maximum gradeability calculation method based on driving torque was got. The method based on the adhe- sive condition for a four-wheel-locked vehicle was also got. So the integrate maximum gradeability calculation method for high military mobility vehicle was given. The actual example shows the method given in the paper was practical. Another discovery ,was that the method to improve the maximum gradeability includes not only increasing the output torque of the engine, and the 1Lransmission ratio, but also the arrangement of the vehicle to improve the adhesive ability between the vehicle and the ground.
