Development and Performance Evaluation of a Bevameter for Measuring Soil Strength [PDF]
Sensors, 2021 The driving performance of an off-road vehicle is closely related to soil strength. A bevameter is used to measure the soil strength, and it usually consists of two independent devices: a pressure–sinkage test device and a shear test device. However, its

Journal of Field Robotics, 2023 Abstract The soil contact model (SCM) is widely used in practice for off‐road wheeled vehicle mobility studies when simulation speed is important and highly accurate results are not a main concern. In practice, the SCM parameters are obtained via a bevameter test, which requires a complex apparatus and experimental procedure.

Fault‐Tolerant Control Strategy for Steering Failures in Wheeled Planetary Rovers [PDF]
Journal of Robotics, Volume 2012, Issue 1, 2012., 2012 Fault‐tolerant control design of wheeled planetary rovers is described. This paper covers all steps of the design process, from modeling/simulation to experimentation. A simplified contact model is used with a multibody simulation model and tuned to fit the experimental data.

Design and performance evaluation of bevameter equipment
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2020 The depth of tilting in agricultural soil is 30–40 cm, which approximates the equivalent contact diameter of tires for the off-road vehicle. The soil thus tends to have an upper loose layer and a hard layer underneath, which leads to changes in the soil ...

A Modified Pressure–Sinkage Model for Studying the Effect of a Hard Layer in Sandy Loam Soil
Applied Sciences, 2021 The applicability of the typical pressure–sinkage models used to characterize the soil’s bearing properties is limited to homogeneous soils (infinite thickness) that have no hard layer. At a given depth, a hard layer can have a considerable impact on the

A systematic approach to reliably characterize soils based on Bevameter testing [PDF]
Journal of Terramechanics, 2011 Abstract Although a lot of information about soil parameter identification exists in literature, there is currently no algorithm who makes use both of state of the art identification methodologies and incorporating statistical analysis. In this paper a state of the art soil parameter identification method is presented including the calculation of its

Predict the Rover Mobility Over Soft Terrain Using Articulated Wheeled Bevameter
IEEE Robotics and Automation Letters, 2022 Robot mobility is critical for mission success, especially in soft or deformable terrains, where the complex wheel-soil interaction mechanics often leads to excessive wheel slip and sinkage, causing the eventual mission failure. To improve the success rate, online mobility prediction using vision, infrared imaging, or model-based stochastic methods ...

An overview of methods to convert cone index to bevameter parameters
Journal of Terramechanics, 2020 Abstract This paper reviews experimental methods for the conversion of cone index measurements to bevameter parameters in support of vehicle soil/tire/track interactions for two general soil types, sand and lean clay. The accurate prediction of traction, motion resistance, and sinkage of tire/tracks off-road requires estimates of soil strength ...
