摘要
提出了一种车辆一路面相互作用的压实-包络模型,以探讨软路面有效不平度形成的机理。该模型包括车辆-路面静压实模型、车辆-路面动压实动力学模型和轮胎-路面印迹包络模型。其中动压实模型考虑了土壤压实的不可恢复性以及车轮-路面相互作用的变界面特点。本文应用上述模型计算了多工况下软路面原始不平度、有效不平度间的关系,计算结果与试验结果基本吻合。
This paper introduces a compacting-enveloping model of vehicle-soil interaction for explaining the form of the effective roughness of terrain. The model includes a static compact model and a dynamic compact model of tyre-soil interaction, an enveloping model of tyre-soil contact area. The non-restoring behavior of compacted soil and the varying interface between tyre and soil have been considered in the dynamic compact model. The relation between the original roughness and the effective roughness of terrain under different con-idtions has been computed by these models, and the results nearly coincide with the results from testing nearly by the authors.
