The stator structure feasibility is verified using the numerical analysis and experimental results 數(shù)值分析與實驗結(jié)果證實了振子結(jié)構(gòu)的可行性。
This paper constructs fe models of srm in detail and analyzes the vibration mode and natural frequencies with the finite element analysis software package , and studies the influence of the stator structure of srm , such as stator poles , ribs , mounting feet , terminal block and structure parameters , restriction condition on the srm vibration behavior , the contrast to experiment result implies that the fea model is close to the real model for analyzing the vibration characteristics of srm 本文基于有限元分析方法,主要研究了定子凸極、底座、散熱筋,加強(qiáng)筋,接線盒等結(jié)構(gòu)以及結(jié)構(gòu)參數(shù)對定子固有頻率和振動模態(tài)的影響,并且研究了約束條件下的sr電機(jī)定子振動特性。本文比較了模態(tài)實驗與有限元分析結(jié)果,表明所建立的二維有限元模型對分析sr電機(jī)的振動特性有較好的精度。
