英文摘要： The electromechanical integrated magnetic gearing based on magnetic field modulation is a new generalized composite drive, in which mechanical, electric magnetic gear and control are integrated. The drive has wide application prospects, because it has characteristics of high density and compact structures, and can be widely used in aviation, aerospace, military, vehicles, and so on. To optimize systematic parameters, and effective evaluate system dynamics performance, must explore the mechanical and electrical coupling dynamics theory. Electromagnetic torque characteristic will be analyzed by integrating analytical method, the finite element method and experiment. Driving mechanism of magnetic gearing will be revealed. Based on this, the electromechanical coupled dynamics model will be established, which contains mechanic system and electric system. By dimension transformation, the inherent characteristics and sensitivity analysis of each subsystem and the integrated system will be completed. Considering the periodical change of electromagnetic mesh stiffness, dynamics stability and forced response will be determined. Based on nonlinear factors, such as electromagnetic mesh stiffness,stable responses, bifurcate behaviors and chaos phenomena of the drive will be analyzed, whether the system contains and does not
