Effects of the windshield inclination angle on head/brain injuries in car-to-pedestrian collisions using computational biomechanics models

Abstract Car-to-pedestrian collision (CPC) accidents occur frequently, and pedestrians often suffer serious head/brain injuries. One major cause is the primary impact with windshield. Here, we use a numerical simulation method to study influence of windshield inclination angle passenger car on pedestrian injury due CPC accidents. The range was set 24°–50°, an interval 2°. results show that significantly affects kinematics exerts different effects head when evaluating various criteria. Regarding peak linear/rotational acceleration acceleration-based criteria criterion (HIC)/rotational (RIC), predictions at secondary stage have no clear relationship (R2 = 0.04, 0.07, 0.03 0.26, respectively), their distributions are scattered. In impact, linear HIC weak trend first decreasing then increasing angle, rotational RIC tend remain relatively constant. cumulative strain damage measure (CSDM) criterion, slightly lower than those increase in observed both stages. When approximately 32°–40°, severity phases generally predicted other angles.
