Multi-Resolution Modeling of Ground Platform Dynamic Performance and Mobility

TARDEC is seeking to advance off-line, real-time, and faster than real-time modeling and simulation methods used for predicting the performance of off-road and on-road vehicles. TARDEC currently uses DADS for off-line simulation and SimCreator to develop real-time multi-body vehicle models. The objective of this proposal is to develop a Multi-Resolution Translating System (MRTS) that will rapidly convert DADS and ADAMS off-line models into SimCreator real-time models. In addition, the MRTS system will generate parameters for use in the NATO Reference Mobility Model (NRMM) as well as OneSAF and other semi automated constructive simulations. NRMM is a simulation tool used to evaluate the on and off-road mobility of wheeled and tracked vehicles. OneSAF is used for constructive simulation as well as the development of doctrine and training materials. During Phase I, the best algorithms to use in implementing the MRTS system are being determined. So far these algorithms have been used to manually convert a HMMWV model from DADS into SimCreator and VehDyn2 (part of the NRMM tool chain). The SimCreator results have been shown to predict vehicle performance well when compared with test data. Phase II will focus on implementing them in an automatic software tool set.
