两轮电动车骑车人头部损伤的生物力学分析OA

The head injuries of the powered two-wheeler(PTW)riders are a common injury in road traffic.It is therefore of great significance to modify the evaluation standard and safety regulations of PTW riders in order to reduce the risks of colli-sion injury.In our study,a human numerical model with detailed anatomical structure of the head was used to simulate the cyclist-vehicle collision,then the biomechanical analysis and injury evaluation of the head were conducted,and the pedes-trian head injury in the pedestrian-vehicle collision was compared and analyzed.The results showed that the kinematic re-sponses of pedestrians and PTW riders were similar in vehicle collisions.However,the biomechanical responses of the head were different,and the risks of head injury of PTW riders were higher than that of pedestrians.Moreover,the riders'grip strength affected the kinematic response of the head,which should be considered in the assessment of the head injury of the PTW riders.
