THE EFFECT OF THE FIBER ORIENTATION ON THE DYNAMIC BEHAVIOUR OF ROTORS IN
WOUNDING-SHAFT

Resumo :
|
|
THE PURPOSE OF THIS WORK IS TO ANALYSE THE DYNAMIC BEHAVIOUR OF SIMPLE-SUPPORTED ROTORS IN WHICH ITS SHAFT ARE MADE OF FIBRE/RESIN IN A WOUNDING PROCESS. THE ORIENTATION OF THE WOUNDING ANGLE IS AN IMPORTANT PARAMETER ON DETERMING THE PROPERTIES OF THE SECTION SUCH AS THE EQUIVALENT BENDING STIFFNESS AND THE EQUIVALENT TORSIONAL STIFFNESS , WHICH CAN MODIFY THE STRAIN ENERGY OF THE SHAFT. THE CAMPBELL DIAGRAM, IN WHICH THE BENDING AND TORSION MODES OF THE ROTOR IS INCLUDED, CAN BE APPRECIABLY CHANGED WITH THE EVOLUTION OF THE ORIENTATION OF THE WOUNDING ANGLE. THIS ANALYSIS CAN BE USED IN AN OPTIMISATION PROCESS MAXIMIZING THE CRITICAL VELOCITIES DISTANCE FROM THE OPERATING ROTATION OF THE ROTOR. |
