Abstract

Lateral loading of the pelvis occurs for both vehicle occupants struck during side impacts as well as pedestrians. This research investigated the load distribution through the anterior (i.e. pubic symphysis) and posterior (i.e. sacrum) aspects of the pelvis for both acetabular and iliac loading. Sixteen male post-mortem human surrogate pelves were tested in quasi-static (n = 4), and dynamic (n = 12) conditions. On the basis of finite element model simulations of a pedestrian being struck at 40 km/hr, a velocity profile for the dynamic tests was prescribed that began at rest (v = 0 m/s) and then achieved a peak velocity of the struck pelvis moving relative to the midline at 4.5 m/s. The average anterior load at fracture from a high - rate acetabulum impact was 1911 ± 929 N compared to the posterior load averaging 1022 ± 630 N. The average anterior load at fracture from a high - rate ilium impact was 418 ± 388 N compared to the posterior load averaging 3107 ± 1473 N.
