摘要

The most similar crash test was identified for each of 100 Crash Injury Research and Engineering Network (CIREN) cases. To quantify the best comparison pairs, a Similarity Scoring Methodology (SSM) with 12 parameters was developed. The results showed 18 comparisons with 'low' (0-6 points), 72 with 'medium' (7-9 points) and 10 with 'high' (10-12 points) similarity scores. Thirty-nine CIREN cases received a similarity point for deltaV (within range: ±16.1 kph [10 mph]). Thirty-seven CIREN cases had a lower deltaV than the crash test. For occupant parameters, seating position and airbag deployment received similarity points most frequently (86% each). Occupant height and weight received points least frequently (41% and 20%, respectively), typically because CIREN occupants were shorter and heavier compared with Anthropometric Test Device (ATD) sizes. This work establishes a standard SSM to be used with future studies and provides information about key differences between crash tests and real-world crashes.
