Abstract
This paper describes numerical techniques for minimizing both average and nominal variation of HIC(d) (head injury criterion (d)) calculated by FMVSS201 FE analysis, while a traditional deterministic FE analysis with nominal input data can minimize only the nominal HIC(d). Importance of controlling the nominal variation of HIC(d) for achieving design target by impact simulations is discussed. For the covering abstract see ITRD E825082.
