- Abstract
Based on full-size vehicle collision test, a new finite element dummy model (FEM dummy) was built in this paper, at the same time the corresponding dummy's material parameter curve optimization method was proposed. For the result of dummy simulation being in keep with that of full scale vehicle collision experiments, it was necessary to scientifically adjust the dummy's structural material parameters and parameters curve. Besides, optimized design of parameters curve was a more complex work. Therefore proposing a method of the curve approximate optimization to meet the design requirements was necessary. First, according to the variation of the curve, we cut it into segments, and redefined them as parameters. Then, using the parameter optimization method, the important parameters was selected which significantly affected the results of the simulation. Finally, using that method obtained the curve which made it consistent with the full-scale vehicle collision test results. In the paper, positive collision chest pressure test of a new FEM dummy as an example, to make sure simulation dummy’ chest pressure peak and spring rate and so on were consistent with full-size vehicle collision dummy data, Use this method to optimization design someone material parameter curve. The result proved that the method could be used to improve the new FEM dummy to meet the needs of the full-scale vehicle collision test.
