Abstract:This report documents the methods and results of testing and analysis to determine optimal locations for RibEye LEDs to measure chest deflection in the WorldSID 50th Percentile Male Dummy. This study determined that the optimal locations for the front and rear chest deflection measurements, along with the lateral-most location, which is currently measured, occur at a linear distance of 35 mm in the x direction with respect to the lateral-most location. Using these optimal measurement locations, estimated deflections resulted in a worst-case error of 9 mm and a mean error of 1.1-1.4 mm. In comparison, measuring deflection in the current tests at only a single location (lateral-most location), would have resulted in a maximum error of 23 mm, and an average error of 4.7 mm. This project supports NHTSA’s mission to reduce the number of deaths and injuries by studying how best to position chest deflection sensors to measure maximum deflection, which is used to estimate injury risk in crash tests.
