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.
