摘　　要：针对实际弹靶试验中存在的靶板不规则和固定方式对试验结果的不确定影响,采用数值仿真的方式对靶板在不同的边界条件和不同几何尺寸下的弹丸耗能做了对比研究。将500 mm×500 mm×25 mm靶板四周完全固定作为基准,通过改变靶板几何尺寸和四周的固定方式,研究在入射条件不变时弹丸出靶速度和弹丸动能消耗的变化,得到的结果显示,平头弹侵彻过程中的耗能较球头弹和锥头弹更多,但靶板面积的变化对耗能比的影响不大,依仿真结果对相关试验方式给出了具体建议。Aiming at irregular and uncertain impact of the actual fixation ballistic tests for the presence of the target plate test results,a study was made of the projectile energy consumption under different boundary conditions and geometries by turning to numerical simulation approach.With fully fixed 500 mm×500 mm×25 mm target serving as a reference,through changing the geometrical size and the way of fixation of the target,a study was made of the residual velocity and projectile kinetic energy with common initial condition.Experiment results show that kinetic energy consumption will be higher for blunt projectiles than for egg-shaped and cone-shaped ones; however,target area had little influence on results.Based on simulation results,some specific suggestions were proposed in terms of methodology for relevant experiments.
