霰弹的二次发射原理与建模分析

THE PRINCIPLE AND MODELING ANALYSIS OF CANISTER FIRED BY TWICE FIRING TECHNIQUE

阐述了霰弹的二次发射原理,建立了相应的数学物理模型,通过数值计算的方法对该模型进行了动力学仿真计算,得到一系列的具有参考应用价值的结果曲线;该数学模型有助于了解各结构参数对二次发射全过程影响的物理规律,和指导霰弹的工程设计工作.

This paper describes the principle of the canister fired by twice firing technique. The corresponding numerical model has been established and simulated using Runge-Kutta numerical method. A series of calculating curves which are useful and valuable for design reference have been gained. The mathematical model can help to understand the physical rules how the structure parameters affect the whole process including the twice firing, and therefore guide the engineering design of the canister.
