Comparative Analysis of Transient Responses of Cylindrical ShellsInduced by Moving and Simultaneous Impulsive Loads

  • 摘要: 为定量分析滑移和同步脉冲载荷下圆柱壳瞬态响应的差异,以不同尺寸的圆柱壳为对象,分别加载滑移和同步脉冲载荷进行数值模拟,研究了平均应变差异随几何特征参数的变化规律。结果表明:对于圆柱壳结构,平均应变差异随径厚比d/t变化的情况与长度相关,厚度变化对圆柱壳的平均应变差异影响较小;对于不同厚度的圆柱壳,平均应变差异随细长比d/l的增大而减小,当d/l≤0.45时,平均应变差异在20%以内。分析结果为相关试验设计和结果评估提供了有价值的参考。
