【摘要】 为研究碳纤维复合板爆炸分离过程,设计2种不同的装药结构,采用AUTODYN软件预先进行数值仿真,通过观测高斯点飞散速度和第四强度理论准则,判断碳纤维复合板断裂情况,并对碳纤维复合板破坏机理进行分析。进一步进行实地碳纤维复合板爆炸切断实验,结果表明断裂效果与仿真计算结果较为一致,有效证明了采用轴向钻孔的装药结构切断效果更优。更多还原

【Abstract】 In order to study the explosion separation process of carbon fiber composite plate, two different charge structures were designed. AUTODYN software was used to carry out numerical simulation in advance. The fracture of carbon fiber composite plate was judged by observing the Gaussian point flying velocity and the fourth strength criterion, and the failure mechanism of carbon fiber composite plate was analyzed. Furthermore, the explosion separation test of carbon fiber composite plate was carried out, the results show that the fracture effect is consistent with the simulation results, which effectively proves that axial drilling charge structure has a better cutting effect.更多还原
