| 摘要： | In this paper,the finite element simulation approach is introduced to the leg protection performance of the vehicle bumper.According to the EEVC pedestrian protection regulations,an improvement scheme is proposed concerning a vehicle pedestrian leg protection performance problem.Energy absorption characteristics of the bumper are improved in the collision process and the harm caused by the bumper is reduced on the pedestrian leg.Compared with the simulation results of the original model,the improved bumper pedestrian leg protection performance have a greater degree of enhancement of knee flexion angle,the shear displacement and tibial acceleration,also met the requirements of the EEVC pedestrian protection regulations. |
