DEVELOPMENT OF JAMA-JARI PEDESTRIAN HEADFORM IMPACTOR IN COMPLIANCE WITH ISO AND IHRA STANDARDS

Head injuries are the most common cause of pedestrian deaths in car-pedestrian accidents. To reduce the severity of such injuries, the International Organization for Standardization (ISO) and International Harmonized Research Activities (IHRA) have proposed subsystem tests in which child and adult head form impactors are impacted upon a car bonnet top. The ISO and IHRA designated the mass of the child headform impactor as 3.5 kg (i.e., the average mass of a 6-year-old child's head), and that of an adult as 4.5 kg. However, such head form impactors have not been developed so far. Therefore, in the present study, new child and adult head form impactors according to the requirements of the ISO and IHRA subsystem test procedures have been designed and developed. The technical specifications, including the moment of inertia, the location of the centre of gravity, the location of the seismic mass of accelerometers, and natural frequency of the impactors, are determined. Then, the results of biofidelity certification tests of the skin of these newly developed impactors are investigated. The results show that the technical specification of the manufactured child and adult headform impactors fulfilled the ISO and IHRA requirements. (A)
