摘要
研究包覆硝酸铵发射药的界面力学性能。采用拉伸剪切和压缩的方法测定在不同硝酸铵含量、不同硝酸铵粒径、不同温度下包覆硝酸铵发射药的界面剪切强度。实验结果表明,随着硝酸铵含量的升高,发射药的界面剪切强度先上升再下降;随着硝酸铵粒径的降低,发射药的界面剪切强度不断下降;随着温度的升高,发射药的界面剪切强度先升高再降低。
Interface mechanical properties of gun propellant coated with ammonium nitrate were studied. The effects of contents and particle sizes of ammonium nitrate and temperature on the interface shear strength of gun propellant were studied by stretching shear and compress experimental method. The results showed that as the content of ammonium nitrate increased, interface shear strength of gun propellant was gradually decreased. As the particle sizes of ammonium nitrate decreased, interface shear strength of gun propellant was gradually increased. And as the temperature rose, interface shear strength of gun propellant were gradually increased then decreased. When ammonium nitrate translated into 13-rhombohedra, compressive strength of gun propellant was increased; when ammonium nitrate translated into tetragonal system, compressive strength of gun propellant was decreased. The study results were valuable for the applica- tion of gun propellant coated with ammonium nitrate.
