Abstract

Based on vehicle collision test, a finite element dummy model (FEM dummy) was built, at the same time the parameter optimization method was proposed in the paper. To improve consistency between the dummy simulation results and results of vehicle collision test, it's necessary to scientifically adjust FEM dummy's material parameters. First, parameter optimal selection applied, the most important parameters were selected. Then, using optimal methods obtained FEM dummy correction result which is similar to that of the real vehicle. Finally, chest pressure result curve of a FEM dummy model in positive collision as an example, main materials parameters of the FEM dummy's chest were selected by parameter optimal selection, then the parameters were modified by optimization method. ensuring simulation dummy’ chest pressure peaks and spring rate are more consistent with vehicle collision result. It further found that the proposed method could be used to improve the FEM dummy model to meet the result of the vehicle collision simulation.
