The Hybrid III 50th Percentile Male Crash Test Dummy is the most widely used crash test dummy in the world for the evaluation of automotive safety restraint systems in frontal crash testing. This dummy is considered to have excellent biofidelity and instrumentation capability. Recent revisions have improved the biofidelity in the femur range of motion and the ankle and foot. The dummy can also be used in many non-automotive applications such as aerospace, high-speed rail, military, special equipment etc.
A curved cylindrical rubber lumbar spine mounts provides human-like slouch of a seated person and mounts to the pelvis through an optional three axis lumbar load cell. The pelvis is a vinyl skin/urethane foam molded over an aluminum casting in the seated position. The ball-jointed femur attachments carry bump stops to reproduce the human leg to hip moment/rotation characteristics. The femur, tibia and ankle can be instrumented to predict bone fracture and the knee can evaluate tibia to femur ligament injury. The foot and ankle simulates heel compression and ankle range of motion.
