【摘要】：表貼式高速永磁電機轉子的永磁體不能承受高速旋轉時產生的離心力,為此研究了一種特殊的大張力環(huán)向纏繞碳纖維護套,由于纏繞時張力的施加,這種碳纖維護套會在永磁體外表面形成一定的預壓力,從而保護永磁體在高速旋轉時不被離心力破壞�；趶椥粤W相關理論,提出了計算纏繞張力作用下纖維層應力分布及其對永磁體預壓力的方法。通過不同張力纏繞實驗確定碳纖維纏繞工藝極限張力,以此為基礎,分別采用解析法和有限元法計算了不同張力制度下的纖維層剩余應力,并在大張力纏繞電機轉子實驗中測試了纖維層提供的預壓力。結果表明,解析法能較為準確地預測出碳纖維纏繞層的應力分布情況及其對永磁體的壓緊力,且解析結果和有限元的誤差很小,和實驗測試結果的誤差在可接受范圍之內,所提出的大張力環(huán)向纏繞碳纖維護套可以滿足永磁電機轉子高速旋轉的要求。
[Abstract]:The permanent magnet of a high speed permanent magnet motor rotor can not bear the centrifugal force produced by high speed rotation. A special kind of large tension annular winding carbon fiber sheath is studied, because of the application of tension during winding. This kind of carbon fiber sheath will form a certain prepressure on the outer surface of the permanent magnet, thus protecting the permanent magnet from being destroyed by centrifugal force when rotating at high speed. Based on the theory of elastic mechanics, a method for calculating the stress distribution of fiber layer under winding tension and its prepressure on permanent magnet is presented. The ultimate tension of carbon fiber winding process is determined by different tension winding experiments. Based on this, the residual stress of fiber layer under different tension systems is calculated by using analytical method and finite element method, respectively. The prepressure provided by the fiber layer was tested in the rotor experiment of the large tension winding motor. The results show that the analytical method can accurately predict the stress distribution of the carbon fiber winding layer and its compaction force on the permanent magnet, and the error between the analytical results and the finite element method is very small, and the error of the experimental results is within the acceptable range. The high tension annular winding carbon fiber sheath can meet the requirement of high speed rotation of permanent magnet motor rotor.
