ABSTRACT:
An apparatus and method is provided for simulating a plurality of bearing orbits. The apparatus includes a first simulator for producing signals indicative of a first simulated bearing orbit; a second simulator for producing signals indicative of a second simulated bearing orbit; a control for varying the rotor journal position for each of the first and second simulated bearing orbits; a control for varying the orbit amplitude for each of the first and second simulated bearing orbits; and a control for modifying the rotor mode shape of the first and second simulated bearing orbits.
