N2 - Through the analysis of the process of the projectile penetrating the concrete target board, using the finite element method to establish a finite element simulation model of it. The modeling method and parameter settings are analyzed during the modeling process, the finite element models of metal aluminum block and rigid polyurethane foam were established, performing the numerical simulations of high-speed collisions. By solving the calculations, obtaining the time-domain signals of the sensor positions, and comparing the overload signals through spectrum analysis. evaluating the influence of two transmission medium on the measured acceleration signal of the sensor. The result shows that the effect of different load transmission media on the overload signal of the sensor under high-speed impact is different, and it proves that super-hard aluminum has better shock-absorbing effect.
