Watch examples of applications of EDEM coupled with MotionSolve and Activate in the design of tracked and wheeled vehicles.
EDEM software, powered by the Discrete Element Method (DEM), accurately represents the behavior or rocks, soils and ores and can realistically model a variety of terrains from soft-soil, dry sand, to rugged gravel surfaces. Integrating EDEM with Multi-body Dynamics tools provides great realism in vehicle mobility simulations and enable engineers to predict the behavior and performance of off-road vehicles in a variety of off-road environments and to study complex manoeuvres which otherwise might be restricted.
In this video EDEM is coupled with MotionSolve to accurately predict the performance of an off-road buggy on different terrains. With EDEM, an extensive range of terrains can be modeled to suit the vehicle test requirements, including sand, gravel or soft soils. The coupling enables engineers to validate the system dynamics under realistic operating conditions. Additionally, analysis on the vehicle component’s performance and the terrain can be conducted to fully understand the test results.
PM-FlexTire deformable tire model for use with EDEM soil models and ADAMS or Motion Solve. PM-FlexTire is an finite element-based tire model that is integrated with the Altair® EDEM™ soft-soil simulation platform and significantly expands what is possible in virtual development of soft-soil mobility. The model provides realistic deformation and high fidelity forces and moments through co-simulation between EDEM and multi-body dynamics (MBD) codes. Included time-varying air pressure model and detailed tread pattern interaction with particles are features unique to PM-FlexTire. Users can create models from tire CAD using various meshing solutions including Altair® HyperMesh® and Gmsh integrations, or use meshes generated from other third party meshing tools. Comprehensive integration with discrete element method (DEM) simulation provides a high level of utility relative to alternatives to support increased scope of virtual development. Simulation complexity and licensing cost of PM-FlexTire and the corresponding integrations are "best fit" for virtual mobility development in soft-soil DEM simulation environments.
