摘要

本文对在森林条件下使用的部分拖拉机轮胎进行了评估。评估的第一部分涉及牵引性能,第二部分涉及轮胎对地面的潜在负面影响。研究是在波兰(下西里西亚地区)低地松树林中的滑行道上进行的。实验使用了 9.5-24、400/55-22.5 和 11.2R24 轮胎,并分析了以下牵引参数:牵引力、拉力和滚动阻力。这些参数是在实验过程中使用安装在拖拉机三点连杆上的特殊测量支架测定的。除牵引力特性外,还测定了车轮对地面的影响--该评估包括足迹面积的测量和接触压力的计算。结果表明,增加轮胎的垂直载荷和降低轮胎的充气压力可使净牵引力分别增加 35% 和 16%。对接触面积和压力的分析表明,最宽的轮胎(400/55-22.5)对地面的负面影响最小。降低充气压力可获得更大的牵引力、更大的接触面积和更小的接触压力。

Assessment of Tractor Tires Used in Forest Conditions in Terms of Traction Performance and Impact on Ground
This paper presents the assessment of selected tractor tires used in forest conditions. The first element of this assessment is related to tractive properties, while the second part concerns the potential negative impact of the tires on the ground. The research was conducted on the skid trail located in a lowland pine stand in Poland (Lower Silesian District). The 9.5-24, 400/55-22.5 and 11.2R24 tires were used for the experiment, and the following tractive parameters were analyzed: traction force, pulling force and rolling resistance. These parameters were determined during the experiment using special measure stand mounted on a 3-point linkage of the tractor. In addition to the traction properties, the impact of the wheel on the ground was determined – this evaluation included measurements of footprint areas and calculation of contact pressures. Based on the obtained results, it was shown that the increase of the vertical load and reduction of the inflation pressure of tires can cause an increase in net traction force of as much as 35% and 16%, respectively. The analysis of contact areas and pressures showed that the widest tire (400/55-22.5) had the least negative impact on the ground. The reducing of inflation pressure allowed to obtain higher traction force, higher contact area and smaller contact pressures.
