| 摘 要： | 针对火炮弹药的特点,建立了弹药的二维轴对称模型,并在圆柱坐标系下,用控制容积积分法导出一组差分离散格式。采用收敛速度快的块迭代法解代数方程组。实验数据表明数值计算的结果和实测值基本一致,经进一步研究可以用于火炮装药的温度测量。

| Abstract: | In this paper the planar axisymmetric model is built according to the characteristic of artillery charge, and in the cylindrical coordinate the difference forms are deduced by using control volume integration method. The block iteration method is used in solving these linear equations. The experiment results indicate that the result of numerical solution is foundamentally consistent with experimental values .The model and program can be used in the temperature measurement of artillery charge by farther study. |
