Occupant Chest Injury Prediction Method Research Based on Vehicle Frontal Impact Pulse

The frontal collision is the most frequent form of collision. Body acceleration is the most intuitive and most easily available test data. There is a close correlation between acceleration and time history of vehicle body collision and occupant injury. The quantitative relationship between the two has been clarified after years of research in the academic community. In this paper, through the study of three vehicle acceleration models, the TESW model has the highest degree of simulation. Through input of the TESW square wave, the dynamic response characteristics between the vehicle body and human chest and the impact of change of parameters on chest injury of occupant are analyzed.
