Computational investigation of the effects of driver and vehicle interior factors on the risk of knee-thigh-hip injureis in frontal crashes
The effects of seatbelt use, muscle tension, lower-extremity posture, driver fore-aft seat position, seat height, and seat angle on the likelihood of knee, thigh, and hip (KTH) injuries during knee-to-knee-bolster impacts in frontal crashes were studied using a finite element (FE) human model. A...
PMHS impact response in low and high-speed nearside impacts
Lateral impact tests were performed using seven male post-mortem human subjects (whole, unembalmed cadavers) to further characterize the response of the body, and in particular the force-deflection response of the lower abdomen, to lateral impact. All tests were performed using a dual-sled, side-...
Comparison of WorldSID and cadaver responses in low-speed and high-speed nearside impact
A series of lateral impact tests was performed in which the WorldSID midsize-male crash-test dummy was struck with a segmented padded impactor that separately loaded the thorax, abdomen, iliac wing, greater trochanter, and mid thigh. Tests were conducted using 8 m/s and 3 m/s initial impact...
Characterization of ovine utero-placental interface tensile failure
Data on the strength of the utero-placental interface (UPI) would help improve understanding of the mechanisms of placental abruption (premature separation of the placenta from the uterus) during motor-vehicle crashes involving pregnant occupants. An ovine model was selected for study because like...
Effects of crash pulse, impact angle, occupant size, front seat location, and restraint system on rear seat occupant protection
In this study, two sled series were conducted with a sled buck representing a compact vehicle. The first series of tests focused on the effects of crash pulse, impact angle, occupant size, and front seat location on rear seat occupant restraint with a generic rear-seat belt system without pre-...
