Oscillations of Rotor Supported on Magnetic Bearings with Impacts in Retainer Bearings
Original language description
Dynamic properties of a rotor supported on two passive magnetic bearings with retainer rolling bearings, are investigated by means of numerical solution of mathematical model of the prototype developed in Institute of Thermomechanics AS CR. , The inner ring of rolling bearing rotates after oblique impact with rotor journal and adds one degree of freedom to the mathematical model of rotor. A new model of impact motion with large amplitudes, introducing radial Hertz stiffness, material contact damping, tangential dry friction and viscous damping was developed. Dynamic properties of such system in the form of 6 differential equations containing strongly nonlinear terms are investigated and the results are presented in the form of response curves. Frequency intervals of periodic, quasi-periodic and chaotic motions are ascertained and influences of various parameters on the dynamic behavior of the studied system are determined.
