Description
Summary:Car-pedestrian accidents account for a considerable number of automobile accidents in industrialized countries. Safeguarding of pedestrians is taking on an increasingly important role in car design. Working Group 17 (WG17) of the European Enhanced Vehicle-safety Committee (EEVC) proposed four impactor models for assessing pedestrian friendliness of a vehicle. In this study, finite element models of adult headform, child headform, upper legform, and legform impactor of pedestrians were created by using LS-DYNA finite element code. The impactor structures follow the descriptions in the reports of WG17 specifications. Simulated certification tests were performed. Some materials were selected from different trademarks of the same kind of materials. The knee of the legform impactor was designed. The parameters of the springs and dampers were adjusted to satisfy the requirements. Results of simulated certification tests for the four impactors are within WG17 limit ranges. These finite element impactor models obtained herein can help evaluate the pedestrian friendliness of vehicle and guide the future development of pedestrian safety technologies.
