摘要

可变形土的研究是确定轮胎、车辆和/或农具设计参数的关键因素之一。这篇文献综述提供了土壤分类、土壤测试、土壤本构模型和用于模拟土壤-轮胎/工具相互作用的数值方法的简要概述。在过去的研究中,使用了经验、半经验和分析土壤模型。然而,由于黏聚力、含水率等大量变量,在详细表征土壤-轮胎/工具相互作用方面存在一些局限性。在过去的几十年里,有限元(FE)方法被用于不同的公式,如拉格朗日、欧拉和任意拉格朗日欧拉来模拟土壤-轮胎/工具的相互作用。近年来,基于连续力学和离散力学的基于颗粒的方法开始应用,并在土的变形和分离建模方面表现出良好的能力。总的来说,这篇文献综述为模拟研究人员提供了轮胎和农具土壤相互作用模型的见解。

A review of soil modeling for numerical simulations of soil-tire/agricultural tools interaction

The study of deformable soils is one of the key factors in determining the tire, vehicle and/or agricultural tool design parameters. This literature review provides a brief overview of soil classification, soil testing, soil constitutive models, and numerical approaches utilized to model soil-tire/tool interaction. In the past, empirical, semi-empirical, and analytical soil models were used in these studies. However, some limitations occurred in terms of characterization of soil-tire/tool interaction in detail due to a large number of variables such as cohesion, moisture content, etc. In the last few decades, the finite element (FE) method was used with different formulations such as Lagrangian, Eulerian, and Arbitrary Lagrangian Eulerian to simulate the soil-tire/tool interaction. Recently, particle-based methods based on continuum mechanics and discrete mechanics started to be employed and showed good capability in terms of modeling of soil deformation and separation. Overall, this literature review provides simulation researchers insights into soil interaction modeling with tires and agricultural tools.
