The work aims to construct a high-precision digital target for human chest to evaluate the injury effect caused by blunt ballistic impact of non-lethal kinetic energy projectile, and then to guide the scientific use of non-lethal kinetic energy projectile to reduce its inherent safety and use safety risks. Based on the numerical verification method in AEP-99-2017 published by the North Atlantic Treaty Organization (NATO), Hybrid Ⅲ 50th, THUMS AM50 and CHEST were selected as three types of chest finite element models. The finite element model of non-lethal kinetic energy projectile L5 was constructed, and the simulation experiments were carried out at the impact velocity of 20, 40 and 60 m/s. The displacement-history curve and the maximum viscosity index VC,max were output. The suitability of the model was verified by comparing the fit of the Bir biomechanical corridor with the VC,max value corridor. The displacement-history curve and VC,max values of Hybrid Ⅲ 50th and CHEST finite element models were in line with the requirements of the three conditions, while the displacement-history curve and VC,max values of THUMS AM50 were out of limit due to the low elastic modulus of the material parameters, which did not meet the requirements of the first and third conditions. Hybrid III 50th and CHEST finite element models can provide a reliable digital target selection basis for blunt ballistic impact damage assessment, a reference for the simulation setting of the endpoint effect of different types of non-lethal kinetic energy projectile blunt ballistic impact on the human chest and technical support for the research and development of protective equipment and optimization of safety standards.
