【摘要】:針對一種起重機用新型永磁同步電機(PMSM)的轉子進行設計和穩(wěn)定性研究,首先建立了起重機用新型PMSM轉子的三維物理模型及數學模型,基于屈曲理論基礎,運用有限元法對轉子模型進行了線性屈曲分析,探討了繩槽對臨界載荷的影響規(guī)律。將線性屈曲及非線性屈曲進行對比分析,在考慮初始幾何缺陷和材料非線性及大變形的基礎上,探討了轉子長度、壁厚、端側板厚度、材料屬性等對轉子穩(wěn)定性的影響規(guī)律。并將幾何/材料雙非線性與極限強度進行對比分析。最后對電機的轉子及主軸進行剛強度校核。通過以上分析,能有效減輕外轉子自重,降低生產成本,縮短生產周期。
[Abstract]:This paper studies the design and stability of a new permanent magnet synchronous motor (PMSM) rotor for crane. Firstly, a three-dimensional physical model and a mathematical model of a new type of PMSM rotor for crane are established, which are based on the buckling theory. The linear buckling analysis of rotor model is carried out by using finite element method, and the influence of rope grooves on critical load is discussed. The linear buckling and nonlinear buckling are compared and analyzed. On the basis of considering the initial geometric defects, material nonlinearity and large deformation, the rotor length, wall thickness, end and side plate thickness are discussed. The effects of material properties on rotor stability are analyzed, and the geometric / material nonlinearity is compared with the ultimate strength. Finally, the rotor and spindle of the motor are checked with rigid strength. Through the above analysis, the self-weight of the outer rotor can be effectively reduced. Reduce production cost and shorten production cycle.
