Abstract
The design of the Hybrid III dummy's hip joint limits the allowable relative rotation between dummy's lower torso and femur assembly. This limited motion is thought to cause abnormally high chest accelerations in some front barrier crash tests. This paper describes static testing and computer modeling to quantify the hip joint range of motion and its effect on dummy chest accelerations. A series of HYGE sled tests were completed using modified hip joints in order to verify model results. (A)
