摘要:
对标准圆筒试验的两种数据处理方法进行了系统阐述和研究，并以一种PBX炸药（HMX/黏结剂：95/5）的Φ50 mm圆筒试验为例，分别采用两种数据处理方法得到试验圆筒的壁膨胀速度、比动能、格尼系数等参量，详细分析和对比了圆筒壁膨胀速度与位移曲线、膨胀比动能与位移曲线。结果表明，在圆筒膨胀早期，新处理方法比传统处理方法能更准确地描述圆筒壁膨胀速度的变化过程，而在膨胀的中后期，两种处理方法所得圆筒壁速曲线偏差较小，且所获得的格尼系数相差很小。
Abstract:
Two data processing methods for standard cylinder tests were described and studied systematically with which the 50 mm cylinder test of a PBX explosive was made as an example. The cylinder test data were obtained in terms of the parameters of radial wall expansion velocity and Gurney coefficient by these two methods. Moreover, the expansion velocityexpansion displacement curve and the ratio energyexpansion displacement curve of cylinder by the two methods were analyzed and compared. The results show that the new processing method can more accurately describe the expansion course of the cylindrical wall than the conventional method at the early expansion stage. While at the middle and latter expansion stage the curves generated from the two methods turn to be close to each other, and the difference for the obtained Gurney coefficient is minor.
