本文总结并分析了在土槽内进行的履带板推力滑移特性的试验结果。土槽内的土壤是取自水稻田的中粘壤土。分析结果指出:增加履刺高度就相应地增加土壤对履带板的最大水平推力(绝对值与拉动履带板的水平牵引力相等)。增加履带板接地压力也使最大水平推力增加。土壤含水量大小影响履带板接地压力所产生的作用。在直刺、人字刺和圆弧刺三种履带板中,其他条件相同时,制造简便的直刺履带板的推力最大。在试验过程中,还观察了在履带板作用下的土壤失效模式。为了深入研究这个问题,寻找提高履带式行走机构通过性,降低能耗的最佳途径,今后要作进一步的探讨。壤含水量大小影响履带板接地压力所产生的作用。在直刺、人字刺和圆弧刺三种履带板中,其他条件相同时,制造简便的直刺履带板的推力最大。在试验过程中,还观察了在履带板作用下的土壤失效模式。为了深入研究这个问题,寻找提高履带式行走机构通过性,降低能耗的最佳途径,今后要作进一步的探讨。
This paper summarizes and analyzes the test results of the thrust slip characteristics of track shoes in a soil tank. The soil in the soil tank is medium clay loam taken from paddy fields. The analysis shows that increasing the stabbing height increases the maximum soil horizontal thrust on the crawler (the absolute value is equal to the horizontal traction of the crawler). Increasing the ground pressure of the track shoe also increases the maximum horizontal thrust. The effect of soil moisture content on the earth pressure on the track shoe. Straight thorn, goblin and arc barbed three kinds of track shoes, the other conditions are the same, easy to manufacture Straight throat shoe thrust maximum. During the test, soil failure modes under the action of track shoes were also observed. In order to further study this issue and look for the best ways to improve the trackability of the crawler traveling mechanism and reduce energy consumption, we should make further discussion in the future.
