摘要:
离心风扇是电机上的重要旋转部件,必须具有足够的强度和刚度,才能保证电机持续有效的安全运转。传统的电机设计中,对离心风扇的设计主要考虑其风压和风量的计算,对风扇的强度和刚度一般仅限于理论计算,随着目前单机容量的不断增大,风扇的直径也随之增大,对其强度和刚度提出更高的要求,传统的计算方法已经不能满足其使用要求,有限元法应用于机械结构的强度和刚度设计,对于离心风扇如此重要的旋转部件,除了离心力对其强度和刚度的影响,风扇运行时,叶片承受较高风压,此均布载荷的作用,也会对风扇的强度和刚度产生重要影响,本文基于ANSYS流固耦合的基础上,先后对风扇进行结构、流场分析,采用顺序耦合的方式,对离心风扇进行强度和刚度分析,具体以某变速恒频1.5 MW风力发电发电机组,双馈风力发电机离心风扇为例,对其进行流固耦合设计,并将计算结果作了详细比较。结果表明,流场对离心风扇的强度和刚度有较大影响,该结果将对电机离心风扇强度和刚度设计提供理论依据。
Abstract:
The centrifugal fan is an important rotation part on the motor,which must have sufficient strength and rigidity to ensure the safe operation of the motor sustained and effective.With theincreasing of capacity and the diameters of the fan,the fan needs higher requirements on its strength and stiffness.The traditional calculation method cannot have satisfied the requirements.Besides centrifugal force the fan blade high wind pressure which plays an important role on strengthe and stiffness of fan when the fan runs.Base on ANSYS fluid-structure interaction,the present paper analysis the centrifugal fan strength and stiffness respectively and made a detailed comparison of the results to prove the improtance of fluid-structure interaction in fan strength as well as stiffness desgin,and take a centrifugal fan of a certain variable speed constant frequency 1.5 MW wind power generator as an example.The results show that the flow field of centrifugal fan has a great influence on the strength and stiffness.This study is helpful for the design f centrifugal fan and for characterization of the strength and stiffness properties of centrifugal fan.
