中文摘要：

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Ф265mm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。

英文摘要：

A loading test by explosive rods to simulate mechanical effects of pulsed X-ray was numerically simulated by fluid-structure interaction method.The 2-D numerical model including a cylindrical shell,two layers of rubbers,nineteen explosive rods and a layer of air was built.Therein,the two rubber materials were described by Ogden hyperelastic models,the explosive rods and their explosion product were described by High Explosive Burn model and JWL equation of state,and the air was described by polynomial equation of state.The numerical simulation was performed by the multi-material ALE method.The physical images,load transmission and structural responses were obtained.The results show that,in the loading test of Ф265 mm cylindrical shell by 19 explosive rods to simulate a cosine-distributed load induced by X-ray,the stress responses at typical locations are basically equivalent.Furthermore,the additive two rubber layers can affect the response characteristics of the shells,and tightly glued interactions can distort the structural responses of shells with small mass and/or low stiffness.
