本文从探讨水田土壤的平板挤压力和下陷深度之间的关系出发,提出用式来描述其关系。研究了轮胎工作时轮齿顶部和轮齿驱动面上的正压力分布特性。应用应力积分的方法推导了驱动轮的牵引力、扭矩和垂直反力。然后进行电算,其结果与土槽上的试验结果有非常好的一致性。试验和理论分析的结果都表明,在高含水量的松软水田土壤中,轮齿高对轮胎牵引性能的作用明显。增加齿高可以提高牵引力和驱动效率。并提出了合适的齿高。
Based on the discussion of the relationship between pad extrusion and depth of paddy soils, this paper presents a formula to describe its relationship. The distribution of positive pressure on the top of gear teeth and the driving surface of gear teeth during tire operation was studied. The method of stress integration is used to derive the traction, torque and vertical reaction force of driving wheels. The calculations then took place with very good agreement with the test results on the soil tank. Experimental and theoretical analysis of the results show that in the high water content of soft paddy soil, high gear tooth traction on the performance of a significant role. Increasing tooth height can improve traction and drive efficiency. And proposed a suitable tooth height.
