Numerical Simulation of Cylindrical Shell Loaded by Explosive Rods (Ⅰ): Fluid-Structure Interaction Simulation

  • 摘要: 对炸药条加载圆柱壳模拟X射线力学效应的试验进行了流固耦合数值模拟。首先建立了包括圆柱壳、两层缓冲橡胶、炸药条和空气在内的二维数值模型,其中,两层橡胶采用Ogden超弹性本构模型描述,炸药条及其爆轰产物采用高能炸药燃烧(High Explosive Burn)模型和JWL状态方程描述,空气采用多项式状态方程描述。然后采用多物质ALE流固耦合算法进行计算,获得了爆炸加载的物理图像、载荷传递与结构响应。结果表明,采用19条炸药条加载265 mm的圆柱壳模拟X射线余弦载荷作用,特征点应力响应基本等效;试验附加的两层橡胶对结构响应特征具有影响,在壳体质量较小和(或)刚度较低的情况下,紧密粘接会引起结构响应失真。
