【摘要】 发射药床挤压破碎的物理仿真是火炮发射装药发射安全性研究的关键技术。本文研制了发射药床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仿真各种火炮发射装药弹底药床点燃前所处的力学环境。用温度远远低于火药气体的惰性气体压缩被模拟的药床 ,既保证了物理仿真的真实性 ,又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。该装置可用于研究发射药床的挤压破碎规律。该试验装置工作可靠 ,可操作性好 ,解决了发射装药发射安全性研究的一个关键问题

【Abstract】 Simulation of the compression and bursting of the charge bed in the chamber is one of the key problems in the study of launching safety of gun propellant charge. In this paper, a new kind of experimental equipment that can be used in the simulation is given. Its structure and working principles are is introduced. Using the semi-closed vessel as the source of compression force, the device can simulate any kind of dynamic environment in a gun propellant charge. Using the low temperature inert gas (N 2) as the compression medium, the device can not only ensure that the simulation is real, but also protect the fragmentized propellant is not in combustion after experiment. Using the device, many simulation experiments have been accomplished, and dynamic environment of propellant fracture is acquired. With the experiments, fragmentized propellant for the compression and bursting of charge bed is obtained. Results of experiments show that the new device can be of use to study the principle of the compression and bursting of charge bed.
