摘要
本文实验测试了具有不同初温和不同粒度的火药床的压缩规律,得到了压缩模量。压缩火药床的应力—应变关系在相对压缩量为20%的范围内仍然是线性的。根据火药床的一维波动方程特征线分析颗粒间应力变化规律。最后给出了有实用价值的颗粒间应力公式。
In this paper, the measured results of propellant beds with different charges and different initial temperatures are presented arriving at a law of their compression and the bulk moduli of the propellant beds are obtained. To the extent that the amount of compression is within 20%, the stress-strain relationship remains linear. With the characteristic method of one-dimensional wave equation, the paper analyses the change of the intragranular stress. Formulus for the intragranular stress is finally given, as seen to be of practical usage.
