Abstract
This paper describes a study that was conducted to determine
sensitivity of several design factors for reducing injury values of
occupants upon side impact using Taguchi method. The full mid-sized
vehicle finite element model is used for the analysis under two
different side impact standards~SINCAP and ECE-R 95. The design
factors that may have major effect on side impacts were selected
and L\d8 orthogonal array was set up for analysis.
Analysis results show that strengthening the passenger
compartment improves occupant protection, especially adding a
pusher foam is significantly lowering the injury values in SINCAP.
No single factor has major effects on rib deflection which is
considered as critical occupant injury criterion in ECE- R 95.
Taguchi method was found to be a useful tool, although its usage
may be limited in crash analysis, for predicting the effect of
various design factors on structure.
