THIS WORK PRESENTS THE DESIGN OF A PROTOTYPE FOR A REDUCED SCALE MULTI-SPAN ROTOR. AN ANALYTICAL METHOD, WHICH INVOLVES THE PRINCIPLE OF LINEAR AND ANGULAR MOMENTUM, WAS APPLIED FOR THE MODELING. FOR THE SIMULATION OF THE SYSTEM RESPONSE WE DID NOT CHOSE A SINGLE VALUE FOR THE PARAMETERS OF THE SYSTEM, BUT WE VARIED THEM IN AN APPROPRIATE RANGE. THIS WAS NECESSARY FOR THE EVALUATION OF THE SENSITIVITY OF THE SYSTEMS RESPONSE WITH RESPECT TO PARAMETERS, SUCH AS SHAFT, BEARING OR ROTOR (MASS AND INERTIA) CHARACTERISTICS. WITH THIS PROTOTYPE IT IS POSSIBLE TO STUDY THE INFLUENCE OF JOINTS IN THE DRIVE LINE AND MISALIGNMENT OF BEARINGS DURING THE OPERATION. THIS PROCEDURE IS HELPFUL TOWARDS A BETTER UNDERSTANDING OF THE DYNAMIC BEHAVIOR OF THIS TYPE OF ROTATING MACHINES (MULTIROTOR-BEARING SYSTEM).
