FE Study on Full Back Support Test

• CAE group in Europe o Using latest Biorid model

• Several load cases o Vary bumper stiffnesses o Vary jacket stiffness o Vary head to restraint friction

• Varying test conditions and sled parameters • Conclusions so far

Conclusions so far

• Possibly detect bumper variations • Possibly detect jacket • Head to restraint friction is critical

o Is this a problem with car seat testing as well?
