Shear Stress-Shear Rate-Time Relationship of Wet and Soft Soils and Its Application (Part 3)——Pull Predication for a Single Track Shoe

摘要: 为了合理地预测湿软地上履带行走装置的推进力,对履带板的推力计算模型进行了修正。修正后的计算模型考虑了土壤受剪速度对其剪切应力的影响。实验结果表明履带板的推力介于考虑和不考虑履剌效应的两个理论值之间。

Abstract: In order to reasonably predicate the pull of track driving device on wet and soft terrain, the pull model of track shoes is revised. The effect of shear rate on shear stress is included in the revised model. Experimental results show that the pull of a singe track shoe is approximately between the two theoretical values including and excluding grouser effect.
