摘要:为深入研究火炮发射安全性的本质问题，本文归纳分析了近年来发射药动态力学强度的研究进展，介绍了落锤撞击实验法、发射药床撞击实验法、发射药动态挤压模拟实验法以及数值仿真等在发射药动态力学强度研究中的应用情况，综述了现有的动态力学强度评价方法，并为今后发射药动态力学强度的研究方向提出建议。
Abstract:In order to study the essence problem of launch safety for gun, the research progress on dynamical mechanical strength of gun propellants were summarized and analyzed. Application status of dropping hammer impact test, gun propellant bed impact test, dynamic compression simulation test and numerical simulation in study of dynamical mechanical strength of gun propellants were introduced, the evaluation methods of the dynamical mechanical strength of gun propellants were reviewed, and suggestions for the further study of dynamical mechanical strength were given.
