摘要:
综述了落锤冲击试验、空气炮试验、分离式霍普金森压杆试验和动态挤压物理仿真试验等在发射药动态破碎研究中的应用状况，介绍了破碎度法、动态活度比法和燃烧渐增因子法等发射药破碎程度的描述方法，并提出建议：在冲击载荷条件下发射药床不同位置药粒的受力特点以及药粒的本构模型和破碎模型还需进一步研究，为描述发射过程中发射药破碎规律提供理论基础。
Abstract:
Drop hammer test, air gun test, split Hopkinson pressure bar test and dynamic compression simulating test are reviewed for their applications in the dynamic fracture study of granular propellant. The characterization methods to describe the fracture extent of propellant such as grains fracture degree, initial dynamic vivacity ratio and combustion increasing factor are introduced as well. It is suggested that further researches in the force of propellant grains in different parts of propellant bed under impact load, constitutive model and cracking model are still needed to provide the theoretical bases for describing the propellant fracture rules in the launch process.
