Purpose and goal
The goals of this project were to develop and implement methods for improved chest injury criteria and implement methods to better predict chest injury criteria. Moreover, to secure that the Ph.D. student within the project could finish his Ph.D.
Results and expected effects
The results indicate that the RibEye chest deflection measurement was higher than the Hybrid III potentiometer deflection. A Normalized Criteria Correction Factor to adjust the chest responses of the Hybrid III can be applied to more accurately reflect the response in a human. This work has developed knowledge and strategic tools necessary for Swedish-made heavy vehicles to retain its position as one of the safest heavy vehicles on the market, which is an important contribution to a continued competitive automotive industry in Sweden.
Approach and implementation
Continued Ph.D. studies to improve the chest injury criteria have been the focus of the project. Moreover, to secure that the Ph.D. student within the project could complete his doctoral studies. This was done by analysing sled tests and full-scale tests with heavy commercial vehicles, evaluation of chest injury risk when the chest is impacting the steering wheel, as well as validation of the proposed method.
