1. Restraint System & Occupant Simulation Capabilities Systems Performance Department August, 2000

2. Restraint System & Occupant Simulation Capabilities Identify and evaluate restraint system parameters with respect to occupant protection –Driver, passenger, seat-mounted side, curtain air bags –Seat belts –Steering wheels –Sensors Perform mathematical modeling (PAMSAFE & MADYMO) Perform dynamic sled tests to evaluate systems Provide design direction to application engineering team Responsibilities - Frontal, Side, Rollover Impact

3. Restraint System & Occupant Simulation Capabilities Restraint Component Level –Bag geometry design (shape, volume, coverage) –Inflator selection (output, slope, multi-stage) –Seat belt (webbing, load limiting, pretensioner) –Steering wheel (strength) –Sensors (fire time) Restraint System Level (simulation of crash tests) –Frontal: FMVSS 208, NCAP, Offset frontal –Side: FMVSS 214, ECE R95, LINCAP, Pole –Rollover: FMVSS 208, Screw Ramp, Curb Trip Systems Performance Process: Use of CAE
