Abstract The parameterization of terramechanics model for the tire off-road traction dynamics modeling relies exclusively on the plate-sinkage test and shear test (not using a tire as the shear tool), according to the existing literature. However, the plate-soil interaction cannot be considered the same as the tire-soil interaction (Plackett, 1985). Part II of this paper investigates whether the tire-soil test can be used to parameterize terramechanics model. The parameterization of the modified Bekker’s model, the Magic Formula tire model, and a bulk density estimation model, using the data from the series of tire and soil tests presented in Part I of this paper (He et al., 2019), is discussed in detail herein. The parameterization approach presented herein can be used to develop tire off-road dynamics models.

在软土上研究轮胎牵引性能的系统试验：第二部分 - 地形力学模型和轮胎模型的参数化

摘要 根据现有文献，用于轮胎越野牵引动力学建模的地形力学模型的参数化完全依赖于板下沉试验和剪切试验（不使用轮胎作为剪切工具）。然而，不能认为板块-土壤相互作用与轮胎-土壤相互作用相同（Plackett，1985）。本文的第二部分研究了轮胎-土壤测试是否可用于参数化地形力学模型。使用本文第一部分（He 等人，2019 年）中介绍的一系列轮胎和土壤测试数据，讨论了改进的 Bekker 模型、Magic Formula 轮胎模型和体积密度估计模型的参数化在此详述。此处介绍的参数化方法可用于开发轮胎越野动力学模型。
