Abstract and keywords

Based on the results of the CHILD project, injury risk curves for Q dummies for frontal impact were presented in 2007. However, the risk curves for the neck were based only on scaling of adult data. In addition, solid risk curves for the abdomen and chest were missing.

The CASPER project is a successor project of the CHILD project which utilises both its own research results as well as those of the CHILD project. One of the CASPER aims is to provide injury criteria specific to the Qdummies, combining results of the CASPER project and results of scaling adult Injury Assessment Reference Values focusing on the neck for younger children, the abdomen for older children and the head in the lateral impact condition. Within the CASPER project (similar to the CHILD project), injury criteria are developed pairing the injuries observed in sixty real‐life accidents with the crash reconstruction dummy measurements. AIS3+ injury risk curves are drawn for the head, the neck, the thorax and the abdomen using the survival method.

For the assessment of abdominal injury risk the CASPER project prioritized an abdominal sensor from three different options and developed the research solution from the CHILD project to a reliable sensor that is appropriate for product development and assessment of CRS.
