Abstract: By combining the standard multi-rigid body dummy model and the finite element human model, the multi-rigid-finite element combined dummy model was established based on the real body characteristic parameters of the victim, and it was applied to a real two-wheel electric vehicle traffic accident. Using the photogrammetric method to reconstruct the scene, we studied the dynamic response of the vehicle after the collision and the damage of the electric vehicle cyclist. The movement of persons and cars after collision is basically consistent with the real situation. The head injury criterion (HIC) value of the dummy, the maximum bending moment of the calf and the von Mises of the skull were obtained through the simulation. The results show that human injury in the simulation are consistent with those of forensic identification. Our study effectively validates the correctness and accuracy of the combined dummy model in accident simulation.
