Abstract:
Objective To carry out simulation optimization and live-fire verification of the bulletproof performance of the boron carbide ceramic/ultra-high molecular weight polyethylene(UHMWPE)fiber composite target board in order to improve bulletproof target boards in light weight and high protection.Methods Firstly,a finite element model of the boron carbide ceramic/UHMWPE fiber composite target board was established based on ANSYS/LS-DYNA.Secondly,the simulation of bullet penetration through different thicknesses of the bulletproof target boards was performed to analyze the protection effect of the bulletproof target board against Type 56 7.62 mm ordinary bullets at a distance of 100 m.Finally,based on the simulation results the target board was optimized by taking the protection effect and quality of the target plate as the main indexes,and the bulletproof performance of the designed target board was verified by live firing.Results The simulation results showed that different thicknesses of bulletproof target boards could achieve effective protection against Type 56 7.62 mm ordinary bullets at a distance of 100 m;the live-fire experiment confirmed the result of the simulation experiment,and indicated that the optimized bulletproof target board was gifted with high protection.Conclusion Rational proportioning of boron carbide ceramic and UHMWPE fiber contributes to meeting the requirements of the bulletproof target board for light weight and high protection,and references are provided for the development of lightweight highly-protective bulletproof target board.[Chinese Medical Equipment Journal,2024,45(11):15-20]
