一种圆筒试验不同数据处理新方法❋
A New Method of Different Data Processing for the Cylinder Test
摘要
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.关键词
