Abstract

The mobility of vehicles in off-road environments is critical for many applications. Predicting the tire-soil interaction is a challenge, especially in non-linear deformable terrain. This paper presents an overview of the bibliographic references on tires–deformable soil interactions after the 2000's, identifying the gaps in the literature. The capabilities and challenges of different modeling frameworks used for mobility (i.e., empirical, semi-empirical, and physics-based) are discussed; special emphasis is given to continuum-based frameworks. A summary of terrain material models used to approximate the behavior of coarse and fine-grained soils is provided with practices used to characterize such materials. A review of tire models for deformable soil navigation and the tire-soil interfaces is provided. Strategies to validate all these models are presented. Finally, the application of these studies for assessing the sensitivity concerning input parameters (e.g., velocity, inflation pressure, and normal load), multi-pass, multi-layered soils, wet soils, and fully integrated multi-body vehicle models are discussed. The final contribution of this review paper is a summary table that synthesizes the extensive bibliographic review. Overall, this work highlights a lack of physics-based trafficability studies in wet and plastic deformable soils. Moreover, studies on contact adhesion, stone picking, multipass, and cornering also need improvement.

轮胎-可变形土相互作用的建模和验证技术综述
车辆在非公路环境中的机动性对许多应用来说至关重要。预测轮胎-土壤相互作用是一个挑战,特别是在非线性变形地形。本文概述了2000年以后关于轮胎-可变形土壤相互作用的参考文献,并确定了文献中的空白。讨论了用于移动性的不同建模框架(即经验的、半经验的和基于物理的)的能力和挑战;特别强调以连续为基础的框架。用于近似粗粒和细粒土壤行为的地形材料模型的摘要提供了用于表征此类材料的实践。本文综述了用于可变形土壤导航的轮胎模型和轮胎-土壤界面模型。提出了验证所有这些模型的策略。最后,讨论了这些研究在评估输入参数(如速度、膨胀压力和正常载荷)、多通道、多层土壤、湿土和完全集成的多体车辆模型的敏感性方面的应用。这篇综述论文的最后贡献是一个综合了广泛的书目综述的汇总表。总的来说,这项工作强调了在湿和塑性变形土壤中缺乏基于物理的可通行性研究。此外,在接触粘附、拣石、多通、过角等方面的研究也有待改进。

期刊介绍: The Journal of Terramechanics is primarily devoted to scientific articles concerned with research, design, and equipment utilization in the field of terramechanics. The Journal of Terramechanics is the leading international journal serving the multidisciplinary global off-road vehicle and soil working machinery industries, and related user community, governmental agencies and universities. The Journal of Terramechanics provides a forum for those involved in research, development, design, innovation, testing, application and utilization of off-road vehicles and soil working machinery, and their sub-systems and components. The Journal presents a cross-section of technical papers, reviews, comments and discussions, and serves as a medium for recording recent progress in the field.
