According to the prior uncoupling analysis and utilizing the Rotation-Superposition Method, a large number of numerical experiments for loading cylindrical shells by explosive rods were performed. The average strain difference at three typical locations was defined as the index for evaluating the test simulation fidelity. It was found that the index mainly relies on the ratio of the rods number to the shell radius, i. e. n/r. The relations between the average strain difference and n/r under four conditions, i. e. the normal (ideal) condition, considering incomplete initiations, explosive rod distribution error and non-simultaneous initiations, were obtained. The investigation provides guidelines for the test design and results evaluation.

利用建立的解耦分析技术,结合旋转叠加法对炸药条加载圆柱壳的试验进行了大量工况的数值模拟。定义3个特征点环向应变的平均差异作为评价等效性的指标,发现了炸药条数量与壳体半径之比n/r对平均应变差异的控制作用,得到了正常(理想)、少量炸药条熄爆、考虑炸药条位置误差以及起爆不同步4种情况下平均应变差异随n/r的变化关系。数值试验结果为炸药条加载试验设计与结果评估提供了指导。

利用建立的解耦分析技术,结合旋转叠加法对炸药条加载圆柱壳的试验进行了大量工况的数值模拟。定义3个特征点环向应变的平均差异作为评价等效性的指标,发现了炸药条数量与壳体半径之比n/r对平均应变差异的控制作用,得到了正常(理想)、少量炸药条熄爆、考虑炸药条位置误差以及起爆不同步4种情况下平均应变差异随n/r的变化关系。数值试验结果为炸药条加载试验设计与结果评估提供了指导。

According to the prior uncoupling analysis and utilizing the Rotation-Superposition Method, a large number of numerical experiments for loading cylindrical shells by explosive rods were performed. The average strain difference at three typical locations was defined as the index for evaluating the test simulation fidelity. It was found that the index mainly relies on the ratio of the rods number to the shell radius, i. e. n/r. The relations between the average strain difference and n/r under four conditions, i. e. the normal (ideal) condition, considering incomplete initiations, explosive rod distribution error and non-simultaneous initiations, were obtained. The investigation provides guidelines for the test design and results evaluation.
