摘要
基于ANSYS-AUTODYN软件,建立SPH砂石撞击2024-T351航空铝合金Lagrange靶板模型,研究靶板分层和叠层顺序对靶板抗撞击特性的影响。数值仿真发现:在靶板相同厚度条件下,单层板的抗撞击性能高于双层板。相同弹体撞击速度下,靶板不同叠层方式具有不同的抗撞击能力。
The model of 2024- T351 aerospace aluminum Lagrangian target impacted by SPH sandstone bullet was established by using ANSYS- AUTODYN software, and the effects of target layer stratification and stacking on the impact resistance of the target were studied.The numerical simulation shows that for the same thickness target, the impact resistant of single - layer target is stronger than the double - layer target. The different stacking method has different impact resistance due to identical velocities of the sandstone.
