摘要
针对目前对凝固模拟的研究多局限于数值模型的算法上,距实时显示尚有一定差距的问题,通过分析熔注炸药凝固工艺特点,结合热力学理论,建立熔注炸药凝固过程热力学模型。基于Matlab界面开发程序,对凝固界面进行数值分析,得到任意时刻装药凝固界面特性方程。通过对逐层凝固过程模拟界面的形成、生长规律进行试验验证。验证结果表明:模拟曲线与试验曲线均近似符合4次多项式形式,模拟结果与测试结果一致,能实现凝固过程的实时模拟。
Most of the solidification simulation study focused on numerical model algorithm, it can not realize real time display. According to the analysis of the characteristics for the solidification process of the melt-cast explosive, the main task is to establish the thermodynamic model by using the combination of experimentation and theoretical analysis from the micro thermodynamics point. Based on the Matlab interface development process, carry out numerical analysis of solidification interface, the characteristic equations at any time are obtained. The simulation and the test curves are both four degree polynomial through the experimentation verification for the formation and the growth law of the solidification interface. The simulation results are consistent with the test, achieving the display of the real-time simulation system of the solidification.
