| 摘 要： | 该文介绍研制成功的发射药床动态挤压破碎物理仿真试验装置。用半密闭爆发器作为压缩动力源，其可控性使该装置能物理模拟火炮发射装药弹底药床点燃前所处的力学环境。用活塞压缩被模拟的药床，有效保护了挤压破碎后的药粒不被点燃。多次试验再现了膛内发射药床的力学环境和挤压破碎状况。该装置真实再现了发射药床的挤压破碎规律，解决了发射安全性研究中的一个关键问题。

| Abstract: | In this paper, a new kind of experimental device that can be used in simulating the extrusion and fracture of charge bed is given. Its structure and working principle are introduced. Using the semi-closed vessel as the source of compression force, the device can simulate any kind of dynamics status in propellant charge at the bottom of projectile. The fragmentized propellant is not combustion after experiment by using the piston as the compression medium. Many simulation experiments are accomplished and the dynamics status of the propellant fracture is acquired. The experimental results show that the new device really repeats the principle of the compression and the fracture of charge bed. The device solves a key problem in the study of launch safety of propellant charge. |
