Study of vehicle front structure crashworthiness based on pole impact with different position
Paper in proceedings, 2013

Because of occupant injury severity in frontal pole impact, this paper conducted a computer simulation study on the frontal pole impact of passenger car. Three types of frontal pole impact FE analysis models were developed according to different impact positions of pole, i.e., no offset, 25%, and 35% left offset relative to the centerline of vehicle. In order to illustrate the characteristics of frontal pole impact, this paper analyzed the impact parameters such as the structure deformation, crash force transmission path and acceleration of car body. The results show that the frontal pole impact was a severe loading condition leading to serious damage to vehicle structure. When it comes to the damage of vehicle, the 35% left offset frontal pole impact mode was the worst whereas the center frontal pole impact mode was the best. The crashworthiness of frontal pole impact could be improved by strengthen bumper, rail, sub-frame and firewall.
