In order to study the impact response of a police riot helmet made of polycarbonate and low density polyethylene, a numerical model was established by using ABAQUS under low energy impact of 5kg impact components. Based on the numerical model, the impact dynamic responses of helmets with different impact energies, different shapes of hammer heads and different impact angles were analyzed. The low energy impact test was carried out on the riot helmet by using the drop hammer impact testing machine. The rules of the impact parameters, such as impact force, hammer head speed, hammer head displacement, hammer head impact energy and helmet absorption energy, varying with time were analyzed during the impact process when the helmet was subjected to 5kg hammer head impact. Based on the experimental results, the accuracy of the numerical model is verified, and the results can provide a reference for the research on the impact resistance of police riot helmets.
