Abstract:
Protection of US military vehicles and its occupants against landmine and IED threats remains an important concern in the area of defense research. Traditionally, military vehicles are designed and developed based on many component and full vehicle tests. Defense Advanced Research Projects Agency DARPA funded the Adaptive Vehicle Make AVM portfolio of programs that developed a set of tools and processes whose goal was to reduce the cost and development time for cyber physical design by a factor of five, while expanding design adaptability and predictability of performance. In order to achieve this goal, the AVM portfolio developed many tools, methodologies and processes. One of the most important tools developed in the AVM program is the survivability assessment tool-Blast Computational Modeling and Simulation BCMS toolset. The BCMS can speed up the survivability performance assessment of a ground vehicle system significantly. This paper describes the capability of the AVM BCMS tool suite and to validate the suite using the three series of physical live fire tests. For simplified structures, like a rigid plate, and a deformable plate, the AVM BCMS prediction agrees well with the live fire test measurements. The prediction accuracy is within 17. In a more complicated structure case such as a blast box, the accuracy of the response predictions using AVM Blast M and S Toolset is decreased. In general, the tool suite overestimates the deformation of a complicated structure. Based on this study, authors believe that the concentrated blast load distribution causes the over-estimation of the structure deformation. Because target structure deformation is over estimated, the more energy is consumed on structure deformation, and the initial velocity as well as the jump height of the target structure is under estimated. This hypothesis needs to be further validated by using live fire tests and more detailed studies.
