| description | In order to improve the accuracy of natural frequency analysis and calculation for the coupling rotor system, a transfer matrix method is proposed to construct a dynamic analysis model of the rotor when conducting modal characteristics research on permanent magnet eddy current couplings. By unifying the magnetic force of the permanent magnet into a zero mass hinge connection, the magnetoelectric force of the eddy current coupling is simplified, and the complex research model is transformed into a mechanical strength problem. The Riccati transfer matrix method is used to perform modal analysis on the rotor that has been equivalently processed, and the natural frequency of the coupling is obtained. On this basis, compare the analysis results with the accurate 3D finite element simulation results. The results show that this method can accurately analyze the natural frequency of permanent magnet eddy current couplings, and the error generated by high-precision simulation model analysis is not more than 8%. This study provides a theoretical basis for the study of the dynamic characteristics of permanent magnet eddy current couplings by comparing the improved calculation data with the finite element analysis results. |
