外来物损伤条件下航空轮胎爆破碎片产生机理及速度分析

以外来物损伤条件下的轮胎爆破为例，研究航空轮胎碎片的形成过程。利用压力容器爆炸模型建立轮胎碎片速度计算数学模型，采用热力学方程和力矩方程确定碎片的偏离角和散射角方程，再根据材料断裂准则得到碎片速度函数。;Aircraft tire burst under FOD (foreign object damage) was shown to illustrate the formation process of debris.Based on the pressure vessel explosion model,the mathematical model of tire debris speed was established.Thermodynamic equation,moment equation and dynamic fracture criteria were used to confirm deflection angle,scattering angle and debris speed
