作者对履刺效应进行了有限元分析。在本文中,讨论了von Mises-Drucker-prayer屈服面。分析和计算结果表明,在一定的总应力水平的情况下,运用von Mises模型,仍可望得到和Drucker-Prager模型大体一致的结果,这就为履刺效应的三维分析创造了条件。计算得到的履带作用下的土体的塑性破坏过程和σ_(max)～σ_(min)图为研究土壤破坏机理和进一步改善履带车辆的牵引性能提供了参考资料。
The author conducted a finite element analysis of the gliding effect. In this paper, the von Mises-Drucker-prayer yield surface is discussed. The analysis and calculation results show that under a certain total stress level, using the von Mises model, it is still possible to obtain substantially consistent results with the Drucker-Prager model, which creates the conditions for the three-dimensional analysis of the gliding effect. The calculated plastic failure process and the σ_(max) to σ_(min) maps of the soil under the action of the caterpillar track provide a reference for studying the mechanism of soil damage and further improving the traction performance of the tracked vehicle.
