摘　　要：利用双向流固耦合的模拟方法,对三维剪切流中不同几何参数的空心球壳和载液球壳的变形特性进行分析。研究发现,球壳在变形的同时伴随着旋转,且球壳上存在着交变应力,交变频率取决于球壳旋转速度。空心球壳相较于载液球壳变形更显著,旋转速度更快。Making use of bidirectional fluid-structure coupling simulation to analyze deformation characteristics of hollow spherical shells and liquid-loaded spherical shells with different geometric parameters in three-dimensional shear flow was implemented.The results show that,the rotation accompanies the deformation of the spherical shell and alternating stress exists on the spherical shell,and the alternating frequency depends on the rotation speed of the spherical shell.The hollow spherical shell’s deformation is more significant and the rotation speed is faster than that of the liquid-carrying spherical shell.
