A predicting method of chest acceleration and its application

The purpose of this paper was to introduce a new predicting method of chest acceleration developed by using numerical approach. In order to predict chest acceleration, the proposed method used two input data, which were chest restraint stiffness and vehicle pulse from actual test. The effectiveness of the method as verified by comparing the difference between original chest acceleration and the predicted one using same vehicle pulse and chest restraint stiffness. Predicted chest acceleration for the 50 kph test by using the data of 56 kph test was found to be in good agreement with chest acceleration of actual test for both belted only and bag and belted test cases. This new predicting method was utilized in parameter study of restraint slope(k) and belt slackness.
