Summary:

Variability in dummy response causes problems when developing a vehicle structure or a restraint system for side impact crashworthiness.A study has been carried out with the objective of quantifying the response variation experienced by the EuroSID, BioSID and USSID dummies, due to dummy positioning and the door velocity time history.MADYMO 3D was used to generate a door trim profile from a 4-door saloon vehicle, and the dummy data was imported from the MADYMO dummy database. A velocity profile from the intruding door was taken from a European ECE 95 side impact crash test, and the three dummy models were then correlated to side impact (M-SIS)(1) sled test results.Design of Experiment techniques were used to develop a three dimensional positioning matrix, which enabled information to be obtained efficiently, but with a minimum number of simulations.For the velocity profile study, each peak and trough was modified in turn to allow the effects of a change to be considered independently, and for the subsequent effect on dummy response to be assessed.The results from the three dummy types in this modeling project, demonstrate the dummy sensitivity to positioning and changes in the intruding door velocity profile
