适用范围: The CRABI dummy was developed to evaluate small child restraint systems in automotive crash environments@ in all directions of impact@ with or without air bag interaction Basic anthropometry for this test device was taken from the University of Michigan Transportation Research Institute Report 85-23. Weight distribution and scaling methods for the infant were approved by the Society of Automotive (SAE) Infant Dummy Task Group. The dummy weighs 17.2 pounds and has a 26.4 inches standing or 17.3 inches sitting height. The Hybrid Ill-like neck and lumbar spine are laterally notched to reduce lateral stiffness The shoulders have flesh support for durability and human-like performance in areas where seatbelt webbing may be placed. In addition@ rubber elements are used in each joint to improve biofidelity and to give the CRABI infant-like range of motion. The CRABI Six-Month-Old design meets all the SAE Infant Dummy Task Group anthropometry@ biomechanical and instrumentation requirements. The instrumentation design incorporates three 6-channel load cells to provide load measurements at the C1@ C7 and L5 vertebrae locations. Accelerometers are used to measure head@ chest and pelvic acceleration and head angular acceleration. All instrumentation is easily accessed
