Abstract
The Department of Forensic Experts in Transportation at the Faculty of Transportation Sciences performed a second set of dynamic passive safety tests of a passenger car (M1 category - Škoda Octavia II) in a child pedestrian collision. The initial and test conditions were similar to those of the first set of tests in September 2009 (Škoda Roomster). The deformations of the contact zones on the frontal vehicle surface were analyzed by a 3D scanning technology (3D handy scanner). Head, thorax and pelvic resultant acceleration, acceleration of knee joint in sagittal direction and contact force on the femoral structure of the dummy (P6 dummy, 1.17m; 22kg) were measured. The aim of these tests is to provide a detailed description of pedestrian kinematics and comparison of primary and secondary impact seriousness.KEY WORDSpassenger car, child pedestrian, primary and secondary impact, dummy instrumentation, injury criteria, 3D scanning
Highlights
Pedestrian safety is nowadays one of the very important criteria in case of the vehicle safety evaluation
Neither Head Performance Criteria (HPC), nor 3ms injury criteria limit value was exceeded in the primary head impact for all the performed tests
The limit value for the secondary impact was only exceeded in case of test No 301 (30.6 kmph); the 3ms criterion was in this case exceeded by 10%
Summary
Pedestrian safety is nowadays one of the very important criteria in case of the vehicle safety evaluation. The risk of the impact consequences for children is only tested by the head impactor test [1]. The reason for this stems from many different scientific studies. They proved that the head is the most frequently injured body part in adults as well as in child pedestrians. This conclusion is more significant in case of child pedestrians as it is demonstrated by the two independent sources in
