Abstract: In the present work are estimated vibration and noise spectrums of a coaxial magnetic gear under no-load operational conditions. The developed approach is used to incorporate three different types of vibration analyzes: random vibration, response spectrum and harmonic response analyzes, based on modal analysis results. Finite element method modeling is implemented by Ansys-Workbench software. Results are obtained and analyzed for mechanical deformation, local accelerations and influence of modal shapes frequencies on vibration spectra during operational modes of a coaxial magnetic gear. Simulations in different rotational speeds and kinematic schemes are performed and results for the vibration and noise spectrums are presented.
