The objective of this study is to clarify the differences of tractive performances generated by the sandy loam-grouser system and the clay soil-grouser system. The tractive performances of the grouser/track shoes are widely researched by previous researchers. However, it is essential to illustrate the influences of the soil properties on the tractive performances of the grouser shoe. Sandy loam and clay soil were used as the test soils for investigating soil parameters in this study. Moisture contents of soil were from 7.5% to 27%, dry basis. Parameters of sandy loam were obtained through direct shear tests, penetration tests, bulk density, and moisture content measurements in laboratory. The grouser shoe was made of steel. Based on the prediction result of tractive performances, the clay soil will always be performed better than the sandy loam no matter which dimension was chosen for single grouser shoe. Based on the experimental results, the grouser height of the track should be 5 cm in order to provide enough traction force, if a tracked vehicle is operated on the environment of either clay soil or sandy loam.

“…Due to the large number of the OVM empirical models that have been proposed in the past, and because of this paper's topic focusing on soil parameters, formulas and other details of the cited OVM empirical models are not presented here, and readers interested in the formulas and more details should consult the references listed, or papers with comprehensive review on OVM empirical models (M. I. Lyasko, 2010), (M. Lyasko, 2010a), (Taheri et al, 2015), (Tiwari et al, 2010). Table 1 Summary of soil parameters for empirical models to assess off-road vehicle mobility.…”

ISTVS embarked on a project in 2016 that aims at updating the current ISTVS standards related to nomenclature, definitions, and measurement techniques for modelling, parameterizing, and, respectively, testing and validation of soft soil parameters and vehicle running gear-terrain interaction. As part of this project, a comprehensive literature review was conducted on the parameterization of fundamental terramechanics models. Soil parameters of the empirical models to assess off-road vehicle mobility, and parameters of the models to characterize the response of the terrain interacting with running gears or plates from the existing terramechanics literature and other researchers' reports were identified. This review documents and summarizes the modelling approaches that may be applicable to real-time applications of terramechanics in simulation, as well as in controller design.

“…The soil with higher water content increases with the increase of shear rate, and it is easier to reach a stable state. The green curve in Figure 6 indicates the water content of 10 % soil, as the shear rate increases, its shear strength changes quickly to level and increases no longer [8][9][10][11].…”

The classical ground soil shear mechanics model is difficult to predict the maneuverability of vehicles under high-speed driving conditions. The shear mechanical properties of soil under dynamic loading are the key factor to research on the ground attachment characteristics of vehicles under high-speed driving conditions. The relationship between the shear properties of the ground soil and the loading rate was analyzed by numerical simulation method. Based on the Janosi shear model of the ground soil, the loading rate and shear rate were supplemented to establish the applicable driving conditions for high-speed and heavy-duty vehicles. The ground soil shearing characteristics model provides a theoretical basis for researching on the vehicle's driving maneuverability under high-speed driving conditions.
