【摘要】：針對(duì)一種起重機(jī)用新型永磁同步電機(jī)(PMSM)的轉(zhuǎn)子進(jìn)行設(shè)計(jì)和穩(wěn)定性研究,首先建立了起重機(jī)用新型PMSM轉(zhuǎn)子的三維物理模型及數(shù)學(xué)模型,基于屈曲理論基礎(chǔ),運(yùn)用有限元法對(duì)轉(zhuǎn)子模型進(jìn)行了線性屈曲分析,探討了繩槽對(duì)臨界載荷的影響規(guī)律。將線性屈曲及非線性屈曲進(jìn)行對(duì)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(chǔ)上,探討了轉(zhuǎn)子長(zhǎng)度、壁厚、端側(cè)板厚度、材料屬性等對(duì)轉(zhuǎn)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(qiáng)度進(jìn)行對(duì)比分析。最后對(duì)電機(jī)的轉(zhuǎn)子及主軸進(jìn)行剛強(qiáng)度校核。通過(guò)以上分析,能有效減輕外轉(zhuǎn)子自重,降低生產(chǎn)成本,縮短生產(chǎn)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.
