为提升含有内嵌结构紧凑型EFP的毁伤效能,文中基于AUTODYN,对含有圆柱体型、圆柱体-圆柱体组合型、圆柱体-圆台组合型内嵌结构的EFP战斗部的成型形状及速度进行了模拟及分析。结果表明:在内嵌结构体积恒定的条件下,其参数在适当范围内变化时,对成型EFP的速度影响不大,但对气动外形影响较大。结论:当选用圆柱体-圆台组合型内嵌结构时,可以获得结构紧凑、长径比及速度较大(文中仿真结果分别为5和1 788 m/s)、气动外形合理的成型EFP。
In order to improve the damage efficiency of compact EFP with embedded structure, the shape and speed of EFP warhead with cylinder-cylinder, cylinder-cylinder combination and cylinder-torus combination inlay structure were studied based on AUTODYN Simulation and analysis. The results show that under the condition of constant volume of the inlay structure, the parameters of the EFP have little effect on the forming speed of the EFP, but have a great influence on the aerodynamic shape. CONCLUSIONS: When the cylindrical-truncated combination structure is adopted, the compact EFP can be obtained with compact structure, large aspect ratio and high speed (the simulation results are 5 and 1788 m / s, respectively) and the aerodynamic shape is reasonable.
