四轮驱动拖拉机在松软坡地上的阻力分析

ANALYSIS OF 4WD TRACTOR RESISTANCE ON SOFT SLOPES

对四轮驱动拖拉机在松软坡地上的滚动阻力作了理论分析。在不同牵引负荷下，对装备不同型号、不同充气压力轮胎的拖拉机在松软坡地上的滚动阻力进行了试验研究。给出了野外试验结果并对其进行了分析讨论。

In this paper,The theoretical analysis of rolling resistance for 4wd tractor on soft slopeswas analyzed.It is that the model of theory was proved by the field experiment of the 4wdtractor equipped with one of three sets of tires which were inflated at one of three inflationpressures. The result of the experiment shown that these factors of anis load and tractionload affected the addition angle for the tractor′s slope upto the tractor worked impossible andthe more the traction load was increased,the more the tractor′resistance was great.
