The Use of the Dracr Airbag Simulation Model as a Design Tool 856064

The airbag simulation program DRACR has been revised to include belt routines. The amended program is used to indicate optimal choice of parameters for a driver supplementary airbag system. As a validation, results from sled tests are given and compared with the computer runs. A good agreement is found for the values of the most essential protection criteria such as chest g's and HIC's. The model has proven to be useful in the engineering process of an airbag restraint system. The interrelationship between important input variables is easily studied. Further validation of the model by other teams is encouraged
