| Abstract: | This paper conducts the research of lower extremities protection of occupant during vehicle frontal impact. The injury mechanism of foot ankle, which is the most frequently injured part of lower extremity, is illustrated. The math model of a dummy lower extremity has been validated by test data. According to the injury mechanism, a new kind of brake pedal has been put forward, and a mechanical analysis has been made using the validated math model. The analysis shows the effectiveness of the countermeasure. |
