FASTER SIDE IMPACT DEVELOPMENT USING MIRA'S SIDE IMPACT SIMULATION (MSIS) TECHNIQUE

A novel MIRA Side Impact Simulation (M-SIS) technique is described, which accurately simulated dummy and door interaction witnessed in full scale crash tests. Seat to door, and dummy to door contacts are reproduced for each test along with the velocity profile required. The technique is based on an adaptation of a HyGe sled system, but could be transposed to most reverse acceleration dynamic test facilities. The system provides an interactive tool designed for the development of interior trim and side impact airbags. It can validate computer modelling simulations, and is an intrinsic part of an integrated development programme. Injury criteria values are evaluated from the relevant side impact dummy. The system has been developed for European side impact legislation, and has been used successfully for American legislation. Typical applications in vehicle development programmes are presented, which demonstrate the role of this technique in reducing lead times. (A) For the covering abstract see IRRD 883972.
