ES-2 Dummy Biomechanical Responses

2002-11-11
2002-22-0018
This technical paper presents the results of biomechanical testing conducted on the ES-2 dummy by the Occupant Safety Research Partnership and Transport Canada. The ES-2 is a production dummy, based on the EuroSID-1 dummy, that was modified to further improve testing capabilities as recommended by users of the EuroSID-1 dummy. Biomechanical response data were obtained by completing a series of drop, pendulum, and sled tests that are outlined in the International Organization of Standardization Technical Report 9790 that describes biofidelity requirements for the midsize adult male side impact dummy. A few of the biofidelity tests were conducted on both sides of the dummy to evaluate the symmetry of its responses. Full vehicle crash tests were conducted to verify if the changes in the EuroSID-1, resulting in the ES-2 design, did improve the dummy's testing capability. In addition to the biofidelity testing, the ES-2 dummy repeatability, reproducibility and durability are discussed.

Investigation of Dummy Response and Restraint Configuration Factors Associated with Upper Spinal Cord Injury in a Forward-Facing Child Restraint

Dummy response and restraint configuration factors associated with a known child injury environment were investigated using a spinal-cord injury accident case, a full-scale reconstruction, and sled simulations. The work is one of several studies undertaken in association with the International Task Force on Child Restraining Systems to support the development of improved neck injury criteria and restraint systems for young children. A two-vehicle crash involving a restrained child occupant was investigated in detail and reconstructed in full-scale at the Transport Canada Motor Vehicle Test Centre using the CRABI 6-Month dummy. Vehicle damage and crush characteristics closely resembled that of the case vehicles. Dummy instrumentation included head and chest accelerometers and upper and lower neck transducers. The case occupant had been facing forward and had sustained a contusion of the spinal cord at T2 that resulted in paraplegia.

SID-IIS Response in Side Impact Testing

The responses of a 5th percentile female ATD in the driver and/or rear passenger positions of 56 crashes are described. The Transport Canada side impact programme consisted of LTV-to-car impacts, car-to-car impacts and IIHS barrier-to-car tests. The majority of the tests involved severe crash conditions for which the vehicles were not designed. The SID-IIs head, chest and abdominal responses were compared to determine the effects of the striking bullet geometry, the angle of impact, the impact point and the self-protective elements of the struck vehicle, including airbag technology and armrest designs. The SID-IIs head responses and deflection measures were sufficiently sensitive to discriminate between the various striking vehicles, crash configurations, airbag systems and armrest characteristics.
