摘要
通过越野汽车砂地行驶的正交试验，查明对应一定的使用条件，有一牵引性、燃油经济性综合效果最佳组合的行驶工况，以车辆的地百行驶效率为评价指标，最佳值可达一般行驶工况的两倍以上。其中，轮胎的气压改变，轮胎的种类，车辆的载荷状况都对其有不同程度的影响。努力提高车轮地百效率初，对越野车辆有重大意义。
Based on the automobile operation experiments on sand,the optimum operation conditions related to tractive performance and fuel economy performance are described in this paper,while the operation efficiency ac is taken as a criterion.The experiment results show that the optimum value generally doubles ordinary value.The tire inflation pressure and the tire size have striking effect on V.and tire load.
