摘要
介绍了落锤冲击试验、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力学性能研究中的应用状况,综述了发射药动态力学性能的研究进展,认为发射药粒的损伤模型、低温脆性、发射药撞击弹底时的力学分析以及发射药冲击破碎的数值仿真需进一步研究。
Application status of drop weight impact test, air gun test, split Hopkinson pressure bar test and dynamic extrusion phys- ical simulation test in study of dynamical mechanical properties of propellant were introduced . The progress of dynamical mechan- ical properties of propellant was reviewed. Considering damage and low temperature brittleness of propellant bullets, the mechan- ics analysis of propellant impacting projectile body and the numerical simulation models of breaking need further study.
