ABSTRACT

Full scale under body blast testing are rather complex and cause a lot of variability in data. The complexity and variability of blast testing can be reduced by a well-developed numerical model that can simulate the various aspects of the loading experienced by the occupant. This paper presented the baseline for coupling LS-DYNA and MADYMO to model the pelvic response of an ATD situated inside the CSIR human response test rig (HRTR), subjected to an under body blast. Two configurations, the flat hull and V-hull were modelled for two different charge sizes 1kg and 6kg. Results were compared to experimental data. Flat hull responses were in comparable ranges, however V-hull simulation responses were much lower.
