    Abstract
  • In order to quantitatively and comparatively investigate the transient responses of cylindrical shells induced by moving and simultaneous impulsive loads, we studied in this work the law of average strain difference varying with geometric parameters by numerical simulations where the two kinds of loads were respectively applied on cylindrical shells with different dimensions.The results show that, for the cylindrical shell, the average strain difference varies with the diameter-thickness ratio, d/t, and the length, that the influence of the shell thickness on the average strain difference is insignificant for specific diameters and lengths.The average strain difference decreases with the increase of the diameter-length ratio d/l, and that when d/l≤0.45 the average strain difference is below 20%.Our results and conclusions provide a theoretical support for relevant experiment design and evaluation.
