| description | The magnetic gearbox for wind turbine has the potential virtue of less maintenance, improved reliability, and overload protection. Dynamic performance analysis plays a key role in its optimal design and ensuring its stable operation. But so far, there are few unified and effective methods for dynamic performance analysis of magnetic gearbox especially for multistage magnetic gearbox. Thus, a nonlinear dynamic analysis method based on load angle is proposed for two-stage magnetic gearbox in this paper. First, the nonlinear dynamic model of two-stage magnetic gearbox is established based on load angle. Second, the analytical expressions of load angle and magnetic torque of magnetic gearbox facing instantaneous shock are obtained by Taylor expansion based on load angle. Third, the dynamic performance of magnetic gearbox under different operating conditions is analyzed. Finally, the simulation results are discussed, and the results show that the accuracy of the proposed analytical method is comparable to that of Runge-Kutta method, which verifies the effectiveness of the proposed method and facilitates its application to the fast dynamic evaluation and optimal design of multistage magnetic gearbox. |
