摘　　要：为验证ProCAST在改性B炸药凝固过程中所得模拟结果的准确性,对改性B炸药凝固模拟进行验证。建立热交换模型,设定改性B炸药实验条件与模拟边界条件,采用ProCAST软件对改性B炸药的凝固过程进行数值模拟,通过模拟其不同时刻的凝固状况,对比不同时刻在凝固界面的2维曲线的拟合情况,验证了ProCAST在模拟改性B炸药凝固的准确性。结果表明,ProCAST程序能够准确模拟出改性B炸药的凝固情况。In order to verify the accuracy of the simulation results of ProCAST in the solidification process of modified B explosives,the solidification simulation of modified B explosives was verified.A heat exchange model was established,and test conditions and simulation boundary conditions of modified B explosives were set.The solidification process of modified B explosives was numerically simulated by ProCAST software.By simulating the solidification states in different moments,the fitting results of 2D curves in the solidification interface at different moments were compared,and the accuracy of ProCAST in simulating the solidification process of modified B explosives.The results show that the ProCAST program can accurately simulate the solidification of modified B explosives.
