Vehicle Deceleration Optimization to Reduce Occupant Injuries

後席乗員の胸部傷害を軽減するための車両減速度の最適化

Vehicle acceleration has a large effect on occupant kinematic behavior and injury risks. In this research, an optimization of vehicle crash pulse was examined to reduce injury measures of rear seat occupants from mathematical simulation. In the optimization, the vehicle crash pulse was improved with the objective function of occupant chest acceleration or deflection. The optimized crash pulse was high acceleration in the initial phase, small in the middle phase and high in the final phase. The optimized crash pulse in the final phase was higher in the case of chest acceleration than that of chest deflection due to inertial force of head and upper extremities.自動車前突時における後席乗員保護の観点から，衝突時の車両減速度の最適化を行った．減少させる乗員の傷害値として，胸部加速度と胸たわみの２つを採用し，車両減速度の最適化により，どの程度乗員の傷害値が低減できるか検証した．また，人体ＦＥモデルを用いて人体にも有効であるか確認した．
