摘要
以列车用异步牵引电机为例,根据其通风结构和传热特点,基于流体力学与传热学的基本原理,在Siemens UG中搭建三维流-固耦合物理模型,进行抽流体操作,运用ICEM软件进行网格绘制.运用流体仿真计算软件FLUENT,采用有限体积法,对该异步牵引电机的流场进行模拟仿真,并比较4种通风结构下的定转子风量配比.通过对流体场详细地分析,得到该电机内部流体特性的分布规律,为该类型电机的设计以及运行提供理论依据.
Taking an asynchronous traction motor for train as an example,according to its ventilation structure and heat transfer characteristics,based on the basic principles of hydrodynamics and heat transfer,a three-dimensional fluid solid coupling physical model of the motor is built in Siemens UG,and the fluid pumping operation is carried out.Then the ICEM software is used to draw the grid,and the hybrid grid is used in this model.Finally,using the fluid simulation software FLUENT,the finite volume method is used to simulate the flow field of the asynchronous traction motor,and the air volume ratio of stator and rotor under four ventilation structures is compared.Through the detailed analysis of the fluid field,the distribution law of the internal fluid characteristics of the motor is pointed out,which provides a theoretical basis for the design and operation of this type of motor.
