Ceramic composite armor is a bulletproof form of bulletproof vehicle, according to the requirements of lightweight bulletproof vehicle, the structural design of spliced ceramic composite armor is carried out. A simulation method based on the finite element software ANSYS/LSDYNA is proposed, for calculating the influence of shape and size of ceramic piece on the bulletproof performance of ceramic plate, and the target shooting test is carried out. By comparing the numerical simulation results with the test results, it is shown that the numerical simulation can well simulate the bullet penetration process on the spliced ceramic composite armour. The bulletproof performance of the ceramic plate spliced by largersized pieces is better than that of the plate spliced by smaller ceramic pieces with the same shape, the bulletproof performance of the ceramic plate spliced by hexagonal pieces is better than that of the plate spliced by regular quadrilateral pieces with the same area.
