Response surface approach for sensitivity study of neck forces in restrained child occupant during side-impact crash
A study is undertaken to characterize the Neck Force (NF) of a CRS restrained 3 year old child occupant involved in lateral and oblique side impact. The Response Surface Method is used to map the parameter sensitivity upon the NF for impact speed of 32.2 km/h (20 mph) both individually as well as...

| Summary: | A study is undertaken to characterize the Neck Force (NF) of a CRS restrained 3 year old
child occupant involved in lateral and oblique side impact. The Response Surface Method is used to
map the parameter sensitivity upon the NF for impact speed of 32.2 km/h (20 mph) both individually
as well as cross interactively. Design of Experiments is used with Latin Hypercube Sampling
involving six predictors. A study of the response plots and statistical data obtained provide insights
on the characteristic of each predictor with respect to the neck forces sustained. Greater parameter
significance affecting neck forces is seen for narrow impact angles (ϕ ≤ 60°). Singularly, the impact
angle parameter is revealed to be largely the most sensitive parameter to affect neck force especially
at narrow angles. The critical range for this is identified to be between angles 50° and 70° while a
secondary critical range is observed for angles below 34°. |
