发射装药挤压应力与破碎规律研究
Study on Extrusion Stress and Fracture Law of Propellant Charge
摘要
Abstract
The extrusion and fracture process of propellant grains under impact loading is numerically simulated. Based on the experiment instrument of dynamic extrusion and fracture of the propellant charge, the new PVDF stress sensor of the propellant charge used in the experiment instrument is developed. The experiment of the dynamics extrusion and fracture of the propellant charge was performed. The experiment results and the simulation ones have good agreement, indicating that the computation theory and model are accurate, the design of the new sensor is reasonable and the new sensor can be used to measure the extrusion stress of the propellant charge in the experiment of the extrusion and fracture of the propellant charge.关键词
