Measurement of Dynamic Friction Coefficient of Several Typical Pyrotechnics

  • 摘要: 摩擦作用对烟火药剂的生产以及使用过程的安全性至关重要,而动摩擦系数是定量研究烟火药剂摩擦做功能力的关键参数。基于MGY-1型摆式摩擦仪的物理模型,结合数值计算方法,得到了测算动摩擦系数的方法。利用该方法测算了硝酸钾、镁铝合金粉及硫磺3种常用烟火药剂单质以及硝酸钾/镁铝合金粉及硝酸钾/硫磺两种混合物的动摩擦系数。结果表明:5种烟火药剂的动摩擦系数为一个范围值;在硝酸钾中加入镁铝合金粉和硫磺后,混合粉末的动摩擦系数较硝酸钾单质减小。从理论上对产生这两种现象的原因进行了分析。
