空心装药通常采用压制成型工艺,为了研究工艺参数对装药质量的影响,采用基于连续介质力学的方法,建立了空心JO‑9159炸药压制过程有限元仿真模型,仿真分析了JO‑9159炸药压制成型过程的相对密度、位移以及等效应力变化规律。在此基础上,针对压制速率、初始相对密度以及摩擦系数3种主要工艺参数对JO‑9159炸药压制成型质量的影响进行了仿真与分析。结果显示:压制过程中JO‑9159炸药粉末主要是轴向流动,靠近阴模区炸药流动相对缓慢;压制速率为0.5 mm·s-1时、摩擦系数为0.25时,成型后装药相对密度较为均匀,回弹量较小。“,”Hollow charges usually adopt compression molding process. Using the method of continuum mechanics, a finite element simulation of the compression process model was established. First, the relative density, displacement and equivalent stress change laws of the pressing process of the JO‑9159 explosive were simulated and analyzed. Then, the influences of pressing rate, initial relative density and friction coefficient on the pressing quality of JO‑9159 explosive are simulated and analyzed. Results show that the JO‑9159 explosive powder flows mainly in the axial direction during the pressing process, and the explosive powder flows slowly near the female mold area; when the pressing rate is 0.5 mm·s-1 and the friction coefficient is 0.25, the relative density of the charge after molding is more uniform and the amount of rebound is smaller.
