Abstract

A biomechanical model was used for experimental studies of leg injuries in car-pedestrian accidents. Human leg specimens including the hip joint were loaded by a concentrated body mass, balanced on an instrumented platform and impacted by a simulated car front mounted on a test cart. Injuries to the different parts of the leg specimens were analyzed for various bumper levels, bumper lead angles, and bonnet edge heights at impact velocities 20 - 28 km/h. An energy absorbing and force limiting bumper was tested at 23 and 42 cm impact levels. A comparison is made of the injuries seen in real accidents and the possibility to mitigate these injuries by modifying the car front is discussed.
