This article presents a review of the equipment used in the process of determining the mechanical strength of soil, in particular with regards to the vertical loads applied. Here, devices incorporating the bevameter approach, i.e. medium and large-scale testers, are discussed. The bevameter technique is described in detail, along with the most common mathematical models relating to the vertical pressure applied to the soil and its compaction. The paper also highlights important phenomena for this type of experiment, such as the scale effect, wall effect, multipass effect, and slip sinkage effect. The article presents the reasons for which plate testers are currently the most commonly used tester type for soil penetration tests for the purpose of terramechanics, including the Next Generation NATO Reference Mobility Model that is currently under development. Investigations towards the influence of the penetration rate on soil penetration are also addressed. Furthermore, the authors also present a selection of their own results of currently ongoing research on the subject of potential influence of the plate grouser on plate sinkage. The results already obtained have made it possible to identify phenomena that are not taken into account in the current research methods, in turn resulting in the development of an innovative plate tester for investigating the sinkage of the running gear components of machines and vehicles in fragmented media.

土壤渗透测试仪 – 最先进的技术 – 第 2 部分 – Bevameter 方法


本文对确定土壤机械强度过程中使用的设备进行了回顾，特别是在施加的垂直载荷方面。这里，讨论了采用波瓦计方法的设备，即中型和大型测试仪。详细描述了贝瓦计技术，以及与施加到土壤的垂直压力及其压实相关的最常见的数学模型。本文还强调了此类实验的重要现象，例如尺度效应、壁面效应、多道效应和滑移下沉效应。本文介绍了平板测试仪是目前最常用的土壤渗透测试测试仪类型的原因，其中包括目前正在开发的下一代北约参考机动性模型。还研究了渗透率对土壤渗透的影响。此外，作者还展示了他们自己目前正在进行的研究结果的精选，该研究涉及板齿齿片对板下沉的潜在影响。已经获得的结果使得能够识别当前研究方法中未考虑到的现象，从而开发出一种创新的平板测试仪，用于研究机器和车辆的行走机构部件在碎片介质中的下沉情况。
