炸药与铝合金的摩擦系数研究

Research on Friction Coefficient of Explosive and Aluminum

采用分离式霍普金森压剪杆对GO-924炸药与铝合金在不同冲击加载条件下的摩擦系数进行研究,得到炸药与铝合金界面间的摩擦系数随时间的变化曲线。结果表明:炸药与铝合金之间的动摩擦系数能维持在0.166~0.176范围之内,且不随冲击加载速率的变化而变化。

The split Hopkinson compression-shear bars are used to investigate the friction coefficient of GO-924 explosive and aluminum under different impact loads. The friction coefficients of interface between explosive and aluminum are obtained. The result shows that the friction coefficient of explosive and aluminum is kept in the range of 0. 166 ~ 0. 176 and is independent of loading.
