Abstract: Dynamic response was investigated for pedestrian struck injury risk ina minicar collision. Vehicle
collisions were simulated using a total human finite element model (THUMS) at speed of 40 km/h with a dummy
of 165 cm and 60 kg. The injury parameters analyzed includes low extremity bending moment, knee joint
bending angle, chest impact velocity, head impact velocity, and head injury criterion (HIC). The results show that
all of the high bending moment, the lower leg bending moment, and the knee bending angle are lower than that
of the injury acceptance levels; both the upper thorax and scapula are at fracture risk due to the impact by the
cowl area having a relative high stiffness structure; and that the head injury risk is low with head impact velocity
of 10.4 m/s, because the impact location is windshield with lower stiffness. Therefore, the injury risk is low when
pedestrian is hit at front conformation for a similar mini car.
