Abstract: In order to study the cyclist's head injury when a electric bicycle's side is in collision with a SUV's front part, MADYMO software is adopted to establish and verify the multi-rigid model of the SUV and the electric bicycle through a case selected from National Automobile Accident In-depth Investigation System (NAIS). On this basis, computer simulation experiments were carried out to study the effects of the electric bicycle's roll angle, the speed of the SUV and that of the electric-bicycle on the cyclist's head injury. The results show that the cyclist's head injury increases first and then decreases with the increase of the electric-bicycle's body roll angle; it increases at the initial collision as the electric-bicycle's roll angle increases, and it would decrease with the acceleration of the SUV and the electric-bicycle's speed.

Key words: electric bicycle, sport utility vehicle (SUV), roll angle, cyclist, head injury
