Existing mobility prediction tools are extensively based on the NATO Reference Mobility Model (NRMM), an empirically derived set of tools developed in the 1970’s. NG-NRMM brings a physics based approach to the mobility problem. By leveraging the latest advances in multi-body physics, ever expanding computing power and significant advancements in remote sensing (GIS) systems, it holds the potential to significantly improve mobility predictions, while supporting the latest ground interaction geometries.(Fully active suspensions, walking geometries, micro sized platforms etc.) While not specifying any one solution, the Cooperative Demonstration of Technology (CDT) scheduled for September 25-27, 2018 will showcase the state of the art in mobility prediction and simulation.
The CDT objective is to provide a platform and audience for the demonstration of the most advanced capabilities in ground vehicle modelling and simulation, with a particular focus on mobility over soft and marginal terrains, typical of ground combat operations. The CDT will include technical sessions on simple and complex terramechanics, demonstrations of field soil sampling in relevant soil types and vehicle mobility displays and simulations using a high mobility platform on representative terrain and soil.
The purpose of the CDT is to demonstrate the capabilities of NG-NRMM in the following seven scientific thrust areas:
1. GIS-Terrain and Mobility Mapping: Identify a GIS-based mapping tool that implements and integrates existing valid mobility metrics (%NOGO and Speed Made Good) in an open architected environment.
2. Simple Terramechanics: Identify most promising existing terramechanics methods supporting NG-NRMM requirements that provide a means of correlating terrain characteristics to remotely sensed GIS data.
3. Complex Terramechanics: Establish a vision for the long-term terramechanics approaches that overcome the limitations of existing models.
4. Intelligent Vehicle Mobility: Identify unique mobility metrics and M&S methods necessary for mobility assessments of intelligent vehicles over a sliding scale of data and control system resolutions.
5. Uncertainty Treatment: Identify the practical steps required to embed stochastic characteristics of vehicle and terrain data to extend and refine the current deterministic mobility metrics.
6. Verification and Validation (V&V): Implement near-term vehicle-terrain interaction benchmarks for verification of candidate NG-NRMM M&S software solutions and lay the groundwork for long term validation data through cooperative development with test organizations standards committees.
7. Data Gaps and Operational Readiness: Refine the operational requirements of NG-NRMM and identify where the gaps exist.
