摘　　要：采用双向流固耦合计算方法,对同步异向6WI型转子密炼机在3种转速下的棱顶端点变形进行模拟计算,得到转子棱顶端点瞬态变形量与相应的变形规律。计算结果表明,转子棱波动呈周期性规律变化,转速越高,相邻的2个波动极值周期越短。随着转速不断升高,左转子最大变形多位于长棱中部,而右转子变形量最大值位于长短棱交界面处。整体看来,右转子变形幅值对转速的敏感度要高于左转子,最大变形位置发生于最大转速下右侧长棱高棱处,最大值达到0.05523 mm,并且,随着转速的改变,最大变形位置也同时发生改变,低棱具有最小波动幅值。对于短棱而言,随着转速的提升,变形愈发剧烈且右转子波动明显大于左转子,中棱具有最大变形量。A two-way fluid-solid coupling calculation method was used to calculate the prismatic tip point deformation of the synchronous anisotropic 6WI rotor compactor at three rotational speeds.Simulation calculations were performed to obtain the transient deformation amount and the corresponding deformation law at the tip of rotor rib.The results were shown that the fluctuation of the rotor edge presents periodic regularity.The higher the rotating speed was,the shorter the period of the two adjacent extreme values of the fluctuation was.With the increase of rotating speed,the maximum deformation of the left-turn was mostly located in the middle of the long edge,while the maximum deformation of the right rotor was located at the interface of the long edge.On the whole,the sensitivity of the deformation amplitude of the right rotor to the rotation speed was higher than that of the left-turn.The maximum deformation position occurs at the high right edge under the maximum rotation speed,and the maximum deformation position also changed with the change of the rotation speed.The overall fluctuation amplitude of the low edge was the lowest.For the short edge,with the increase of rotating speed,the deformation became more severe and the fluctuation of the right rotor was obviously greater than that of the left-turn,while the middle edge had the maximum deformation.
