Abstract : The following validation study analyzes rigid multibody dynamic the US Army's High Mobility Multipurpose Wheeled Vehicle (HMMWV) using the Dynamic Analysis and Design System (DADS) computer code and the US Army's Vehicle Dynamic Module (VEHDYN) computer code. Simulated testing of the two vehicle models was conducted over non-deformable discrete obstacles and non-deformable continuous undulating terrains. Results from the model simulations (vertical acceleration time histories, frequency distributions, and absorbed power calculations) were compared with dynamic responses of the HMMWV during field tests conducted by the US Army Engineer Waterways Experiment Station.
