Quantitative study of aortic strain injuries originating from traffic accidents.

Aortic injuries are the second leading cause of death after head injuries due to traffic accidents, and strain-induced injuries are becoming increasingly prominent. The quantitative study of aortic strain injury allows for a rapid assessment of the degree of aortic injury after an accident and timely diagnosis of the pathology of aortic injury. It is more reliable than diagnosis based on clinical symptoms alone and it is faster than diagnosis based on imaging.

Comparison of the effectiveness of rotating seats in autonomous vehicles and airbags in traditional vehicles to minimize head injuries in frontal crash.

We analyzed and compared the effectiveness of the rotating seat of autonomous vehicles and that of an airbag in traditional vehicles as head protection measures in a frontal crash. Driver frontal crash models of traditional and autonomous vehicles and a head finite element model were established. Four evaluation indexes were used for comparison.
