搅拌槽内流体作用力下搅拌桨叶的应力计算

Calculation of stress of an impeller acted by liquid in a stirred tank

文中利用搅拌槽流场模拟的数据 ,结合有限元分析软件ANSYS ,对翼形CBY搅拌桨进行了应力分析。文中采用了一种插值方法 ,实现了从流场数据到有限元模型载荷的数据交换 ,并对一个实验搅拌桨进行了应力分析 ,其分布规律与参考文献的实验测量值一致。

The stress of an airfoil impeller CBY acted by liquid in a stirred tank was analyzed by using a finite element method. A new method was developed to exchange the data from the Computational Fluid Dynamics(CFD) to a finite element model. The stress distribution of the impeller predicted by the finite element method is in good agreement with experimental results given by the literature.
