About CREATE- GV
The CREATE-GV (ground vehicles) project was recently established to develop physics-based, high performance computing (HPC) tools to enhance ground vehicle concept development, inform requirements development, and provide requisite data for trade-space analysis, with an ultimate goal to positively impact cost, schedule, and performance with significant reduction in risk for the acquisition community. The project is developing software tools for analyzing ground vehicle concept designs and the mobility performance of wheeled and tracked ground vehicles, covering manned and unmanned vehicle applications. The software tools include Mercury and additional supplementary expansion tools that greatly enhance and extend the overall capabilities of Mercury. These combined tools enable virtual assessment of performance for proving ground and mission-level based mobility requirements and are optimized for producing performance data for use in trade space analysis, enabling consideration of numerous design trades early and often throughout the acquisition lifecycle.
Mercury, the flagship CREATE-GV product, is a physics-based co-simulation software tool for simulating proving-ground type developmental performance tests used as acquisition requirements. Through its co-simulation framework, Mercury integrates physics domains such as vehicle dynamics, powertrain, tire- soil and track-soil interaction, and driver and control models. It can automatically simulate multiple performance tests such as ride quality, discrete-obstacle shock, soft-soil mobility, sand slope climbing, maximum speed, lane change stability, and circular turn stability. Mercury utilizes detailed 3-dimensional vehicle models that include component representations for suspension, driveline, powertrain, steering systems, chassis, tires, tracks, and more.
The Mercury expansion tools include the Mobility Analysis Tool (MAT) and the Ground Vehicle Interface (GVI). MAT is a model-based computational tool for predicting mission-level mobility performance metrics used as acquisition requirements. MAT can account for a wide variety of terrain, seasonal, and weather conditions to assess the suitability of vehicles for missions in multiple regions around the globe for differing terrain types and climatic zones. GVI is a web-based user interface providing a simplified, intuitive process to launch HPC simulations using Mercury and MAT, produce performance data required for robust trade space analysis, and enable effective model data management and long-term knowledge reuse. GVI is accessible through the HPCMP Portal site, which is accessible to HPCMP users via CAC login from any internet access point.
