Based on the local treatment method, the finite element model for the dummy’s chest with Chinese 50th percentile pilot parameters was established. And the dynamics performance of the chest was simulated according to the test requirements. Comparisons were made between the results obtained by simulation and tests, which indicated that the solving domain of the mechanical model and the scale of the calculating model are greatly reduced by using the simplified chest model, the calculating proficiency is improved, and the simplified chest model has good anthropopathic integrality. It was found that the simulation method used to analyze the dynamics performance of the dummy’s chest is a valid and correct approach. The research could be a reference to the simulation of the dynamics performances of the dummy’s other parts and the improvement of the dummy’s structures.
