Development of an Instrumented Rate-Sensitive Abdomen for the Six-Year-Old Hybrid III Dummy
Published May 23, 2007 by Society of Automotive Engineers of Japan in Japan
Event: JSAE Spring Conference
A rate-sensitive abdomen for the 6-year-old Hybrid III ATD was developed using a silicone rubber shell filled with viscous fluid (silicone or glycerin). A novel displacement measurement system using a ratio of color intensity of light was also developed. Multiple LEDs are used as targets on the front of the abdomen and a sensor is placed against the lumbar spine. The front of the pelvis was trimmed to improve the fit of the abdomen in the pelvis. The chest rotary potentiometer, housed in the abdominal area, was replaced by a telescoping displacement sensor (IR-TRACC) entirely contained within the chest.
