本文综合了国内外越野汽车通过性的评价方法,结合汽车在松软土地上的行驶状况、提出了用三项主要评价指标(最大单位挂钩牵引力,发挥最大单位挂钩牵引力时的轮胎效率;行驶效益)和三项辅助评价指标(给定土壤条件下的最大车速;最小相对转弯半径;相对车辙深度)来评定越野汽车通过性的方法,并用该方法在砂地上对五种汽车的通过性进行了比较评价。其评价结果与理论分析基本一致,这是一种考虑较全面的综合性评价方法。
In this paper, a comprehensive evaluation method of cross-country vehicle passing sex is put forward. Combining with the driving situation of the car on the soft land, the paper presents three main evaluation indexes (the tire efficiency and the driving efficiency when the maximum unit is linked to the traction, And three auxiliary evaluation indexes (the maximum speed under given soil conditions; the minimum relative turning radius and the relative depth of rut) were used to assess the passability of off-road vehicles and the comparison of five vehicles’ passing through sand Evaluation. The evaluation results are basically the same as the theoretical analysis, which is a more comprehensive and comprehensive evaluation method.
