Abstract
Abstract: In order to reveal the non-lethal injury mechanism of rubber projectile and improve its safety service level, the 18.4 mm rubber projectile finite element model and the improved chest blunt injury assessment model are constructed and verified. The virtual impact test experiments under different loads are carried out, and the stress-time response and deformation-time response data are obtained. The results show that the time to reach the peak stress (less than 0.2 ms) is much shorter than the time to reach the maximum deformation variable (4~5 ms), which means the damage is not caused by the impact itself but by the transmission and diffusion of energy. Based on the Viscous Criterion, the damage conditions at different impact speeds are evaluated, and the safe use recommendations of the 18.4 mm rubber projectile under different shooting distances are given.
