干沙性土壤区履带附着能力分析

履刺是保证履带车辆附着性能发挥的措施之一,通过履刺对土壤的剪切作用,能有效地提高履带车辆的附着能力。但在干沙性土壤地区(如中东沙漠地区),“外军”履带车辆的履带板形状却与传统履带板的形状有很大差别。为此,应用土力学基本理论分析了在沙漠土壤条件下履刺的作用。结果表明,在沙漠地区工作的履带车辆,履刺的作用是有限的或与无履刺履带板的作用是基本相同的;同时,考虑到履刺的扰土作用,可以得出履刺的作用反而是得不偿失的。

The Adhere Ability of Pedrail When Working on Desert Soil

Through cutting the soil, the pedrail arista is a way to increase adhere force. But when it is used in the desert area, such as middle east, the American army it, s shape and height is concerned with the property of soil. On the desert soil area, there is a lack of water and clay, the soil unable to bear the weight of vehicle. After referring the US army, s pedrail, this article use the theory of soil force to analyze the working of arista. The result shows there is no difference between having arista and no arista. Concerning the disturbing, it is better not to use the arista.
