减少滚动阻力是提高拖拉机牵引性能的一个重要途径。轮子滚过后,形成沟辙(下陷),在形成沟辙过程中,所受到的阻力损失,往往是滚动阻力的主要组成部份。(滚动阻力除包括土地变形阻力外,往往还包括推土阻力,拥土阻力;在充气轮胎,还有轮胎本身的变形损失,但在一般情况下,以土壤变形阻力为主)。要想降低滚动阻力,就要分析影响土壤变形阻力的主要因素,进而准确地预计土地变形阻力。
Reduce the rolling resistance is an important way to improve tractor traction performance. After the wheel rolled, the formation of the groove (sag) in the formation of the course of the resistance loss suffered, often the main component of the rolling resistance. (In addition to rolling resistance, including the resistance to deformation of the land, often also include the resistance of soil resistance, soil resistance; in the pneumatic tire, there are deformation losses of the tire itself, but in general, the main soil deformation resistance). To reduce the rolling resistance, we must analyze the main factors affecting soil deformation resistance, and then accurately predict the deformation resistance of the land.
