Abstract
A numerical model was established by using ABAQUS for a police riot suit which was composed of nylon, foam polyethylene and sandwich board under low energy impact provided by 7.5 kg ball head impact assembly. The impact force and the energy absorbed by the riot suit are numerically analyzed, and the structure of the riot suit is improved. The results show that the peak impact force of the improved riot suit is reduced by 11.7%, and the energy absorbed by the improved riot suit is increased by 12.1%. The accuracy of the numerical model is verified by comparing the low energy impact test of the riot suit. The obtained results can provide theoretical guidance for the structural design of the police riot suit.
