摘　　要：把固体域离散成梁单元,流体域划分为若干段,对流体段离散成六面体单元,建立了固体域整场求解、流体域分段求解的分区耦合模型,描述了耦合界面信息传递方法。为了避免同种偏心度重复计算,还提出了环空流体特性描述数据库。A partitioned coupling model was founded in which solid domain was totally solved and fluid domain was separately solved by dispersing the solid domain into beam element,dividing the fluid domain into some sections,dispersing the fluid section into hexahedron unit,and the transfer method of the information of the coupling interface was described.A database of describing the characteristics of annular fluid was proposed for avoiding the repeated calculation of the same eccentricity.
