| Abstract: | Aeenrding Chinese and international relative regulations on automobile pedestrian protection, the paper builds the FEM of headform impaetor. By further research on the model characteristics based on MODYMO, the paper has fixed key de- sign parametet for headfim impactor and has developed a program, which can quickly fix the parameters of headform far 3.5 kg and 4.5 kg （including 2.5 kg and 4.8 kg） and can buiht numerical model. The model is verified by static and dynamic ealila＇alion tests and it can be used in the development of automobile pedestrian protection. |
