| Abstract: | A two degree of freedom (2DOF) Mass-Damper-Stiffness model of a rotor on Metal Rubber-Active Magnetic Bearing system is used to investigate the contributions of Metal Rubber damping to the Modal damping response of the system. The system modelling and analysis were carried out in Patran and Nastran. Patran is a computer-aided design, processing and post-processing software while Nastran is an FEA solver. This work further investigates the interaction between the stiffness and damping properties of Metal Rubber-Active Magnetic Bearing and the system's response to modal damping using General Sensitivity Analysis. The results i) affirms that with MR, the flexibility of ordinary AMB is increased: a favourable condition for support of light flexible rotors, ii) show that the frequency and damping of the rotor-supported systemis sensitive to the dynamic properties of the MR material. |
