“…Each timestep involves solving a block-sparse mixed linear complementarity problem (mlcp) that also support modelling of frictional contacts and secondary constraints for joints and motors. The present paper is motivated by the exploration of ground vehicles on deformable terrain [21]. Current solutions enable simulation of complex vehicle models with real-time performance but not with dynamic terrain models firmly based on solid mechanics in three dimensions.…”

A method for simulation of elastoplastic solids in multibody systems with nonsmooth and multidomain dynamics is developed. The solid is discretised into pseudoparticles using the meshfree moving least squares method for computing the strain tensor. The particle's strain and stress tensor variables are mapped to a compliant deformation constraint. The discretised solid model thus fit a unified framework for nonsmooth multidomain dynamics simulations including rigid multibodies with complex kinematic constraints such as articulation joints, unilateral contacts with dry friction, drivelines, and hydraulics. The nonsmooth formulation allows for impact impulses to propagate instantly between the rigid multibody and the solid. Plasticity is introduced through an associative perfectly plastic modified Drucker-Prager model. The elastic and plastic dynamics are verified for simple test systems, and the capability of simulating tracked terrain vehicles driving on a deformable terrain is demonstrated.

“…By using the simulated model they studied on the performance of the wheeled vehicle on deformable terrains tried to construct an applied framework for the complex problem of soiltire interaction. They used most of the developed models to evaluate the material properties and simulation input parameters (Taheri et al, 2015;Ivanov, 2010;Li et al, 2007;Lee, 2015;Xia and Yang, 2012;Grecenko and Prikner, 2014;Hildebrand et al, 2008;Lee and Gard, 2014). The correlation between wheel of vehicle and terrain were investigated from different aspects.…”

“…Physics-based models provide a more detailed, complicated, and complete analysis. Physics based models, especially finite element methods (FEM) and discrete element methods (DEM), have high computational costs and time requirements (Taheri et al, 2015). Despite the costs, there has been progress in the implementation of both the FEM and DEM methods for terramechanics applications (e.g., Knuth et al, 2012;Xia, 2011;Smith and Peng, 2013).…”

A gap in off-road mobility is the availability of the test data necessary for the development and validation of tyre, track and soil models. This paper presents the results from a multi-year program to create the database records for off-road vehicle environments (DROVE), a consolidated database of laboratory and field test results. A fine-grained soil component was added to DROVE by compiling 2657 test results. Performance parameters including drawbar pull, motion resistance, torque, sinkage, and slip were included in the database. The database was used to evaluate the accuracy of existing algorithms used in the vehicle-terrain interface (VTI) model. The results indicated that the VTI algorithms can provide reasonable predictions for a few parameters but for others, such as motion resistance, further improvements are warranted. 4 F. Vahedifard et al.The DROVE dataset can be used for several applications including evaluation of existing mobility models, development of improved algorithms, and validation of numerical simulations.
