Abstract In the United States, the NATO Reference Mobility Model (NRMM) has been used for evaluating military ground vehicle mobility and the Vehicle Cone Index (VCI) has been selected as a mobility metric. VCI represents the minimum soil strength required for a vehicle to consistently make a specific number of passes, usually one or fifty passes. In the United Kingdom, the Mean Maximum Pressure (MMP) has been adopted as a metric for assessing military vehicle cross-country mobility. MMP is the mean value of the maxima occurring under all the wheel stations of a vehicle. Both VCI and MMP are empirically based. This paper presents a review of the basis upon which VCI and MMP were developed, as well as their applications to evaluating vehicle mobility in practice. With the progress in terramechanics and in modelling and simulation techniques in recent years, there is a growing desire to develop physics-based mobility metrics for next generation vehicle mobility models. Based on the review, criteria for selecting physics-based mobility metrics are proposed. Following these criteria, metrics for characterizing military vehicle traction limits and traversability on a given operating area are recommended.

对下一代车辆移动模型的移动度量的回顾

摘要 在美国，北约参考机动性模型（NRMM）已被用于评估军用地面车辆的机动性，并选择车辆锥体指数（VCI）作为机动性指标。VCI 代表车辆始终通过特定次数（通常为 1 次或 50 次）所需的最小土壤强度。在英国，平均最大压力 (MMP) 已被用作评估军用车辆越野机动性的指标。MMP 是车辆所有轮站下出现的最大值的平均值。VCI 和 MMP 都是基于经验的。本文回顾了开发 VCI 和 MMP 的基础，以及它们在实践中评估车辆移动性的应用。近年来，随着地形力学以及建模和仿真技术的进步，人们越来越希望为下一代车辆移动模型开发基于物理的移动度量。在审查的基础上，提出了选择基于物理的移动性指标的标准。遵循这些标准，推荐用于表征给定操作区域的军用车辆牵引力限制和可穿越性的指标。
