Abstract: In order to study impacts of torso yaw angle, torso anterior angle and participant's collision speed on cyclist's HIC in frontal collision accidents between electric bicycle and SUV, a simulation experiment was designed based on multi-rigid body model of SUV and electric bicycle verified by MADYMO software. The results show that the HIC value will gradually decrease as cyclist's torso yaw angle increases, and also do so as torso anterior angle increases when electric bicycle's speed doesn't exceed 15 km/h or SUV exceeds 50 km/h. Otherwise, it will increase first and then decrease with the increase of the torso anterior angle when the former exceeds 15 km/h or the latter no more than 50 km/h. Cyclist's head injury can be reduced by increasing torso yaw angle and anterior angle simultaneously in advance.

Key words: electric bicycle, sport utility vehicle (SUV), cyclist, torso, yaw angle, anterior angle, head injury criterion(HIC)
