摘　　要：设计电磁动态密炼机四棱异步剪切型转子,建立在电磁振动条件下转子的三维数学模型,并运用专业流体软件Polyflow动态模拟分析转子流场的压力场、速度场、剪切速率分布、粘度分布、混合指数分布和浓度场。结果表明:在电磁振动条件下,转子流场出现最高压力、最大速度、最大剪切速率和最大质量浓度的时间缩短,转子突棱处的粘度很小,转子平滑处的粘度较大,混合指数较小,从而使胶料快速完成混炼,提高混炼效率,降低混炼能耗。The four edged asynchronous shear rotor of electromagnetic dynamic mixer was designed,and the three-dimensional mathematical model of the rotor under the condition of electromagnetic vibration was established.The flow field of the rotor was dynamically simulated and analyzed by using professional fluid software Polyflow,including pressure field,velocity field,shear rate distribution,viscosity distribution,mixing index distribution and concentration field.The results showed that,under the condition of electromagnetic vibration,the time to reach the maximum pressure,maximum velocity,maximum shear rate and maximum mass concentration in the rotor flow field was shortened,the viscosity at the convex edge of the rotor was very small,the viscosity at the smooth part of the rotor was large,and the mixing index was small.Thus,the rubber compound could be mixed quickly,the mixing efficiency was improved,and the mixing energy consumption was reduced.
