“…There is, however, a concern regarding the influence of normal load on the pressure-sinkage relationship as described in (Ding et al, 2014). By replacing the normal load as the product of the plate area and pressure (Ding et al, 2014) in Eq. 21, and substituting the Eq.…”

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.

For a better original state and scientific value of lunar soil samples, research on the impact of drill bits on the perturbation rate based on DEM was carried out. A simulated model of lunar soil was established based on the linear adhesion contact model. The parameters of the model were determined by matching between the mechanics and discrete elements. The evaluation criteria of the original states of the lunar soil samples were built on the basis of actual project needs. Based on this, some simulations for the drilling and sampling of lunar soil with different drill bits were carried out. The impact of drill bit parameters, such as internal diameter, cutting angle and height of bottom-out blade on the perturbation rate, was studied. It is shown by the results that the perturbation rate decreases with both the internal diameter and the height of the bottom-out blade, and there is a minimum value with cutting angle. For the best perturbation rate of lunar soil samples under the constraint conditions of the project, the internal diameter should be 18 mm, cutting angle should be 90°, and height of bottom-out blade should be 5 mm.
