A PRACTICAL DATA PROCESSING METHOD FOR VEHICLE DECELERATION DURING IMPACT

Deceleration data of vehicle occupant compartment contain fundamental information related to structural integrity and vehicle/occupant interaction as well. This paper describes the selection of filter characteristics relevant to identification, from noisy accelerometer data on the frontal impact, of the underlying crash pulse shape to be used as an input to analytical simulation model or as a loading condition to sled test. By comparing the response of occupant to full scale experiment among those by numerical calculation, where the occupant is represented by a two-dimensional five mass mathematical model, stimulated by vehicle deceleration processed through filter with various characteristics, the appropriate filter characteristics are discussed in relation to HIC (Head Injury Criteria) and the displacement of the occupant.
