Aimed at traffic accidents in untypical contact state such as side impact accidents and oblique impact accidents, the relationship between optimized parameters and input parameters was fitted by the combination of orthogonal test and polynomial regression analysis based on a real-world accident, and the initial parameters in this accident was optimized. Simulation results show that this method has a high degree of accuracy in optimizing initial parameters. Meanwhile, the injury of pedestrian in numerical simulation agreed with the conclusions of medical report, which further verified the reliability and rationality of simulation.
