EFFECT OF UNCERTAINTY OF THE SUPPORT STIFFNESS, DAMPING AND UNBALANCE EXCITATION ON DYNAMICAL PROPERTIES OF THE TURBINE ROTOR OF AN AIRCRAFT ENGINE
Original language description
The behavior of rotor systems is influenced by a number of parameters whose values are not exactly known or which depend on operating conditions and can change during the rotor running. The presented article deals with analysis of a free turbine rotor ofan aircraft engine taking into account the uncertainties of its supports stiffness, damping and unbalance excitation. The investigated rotor consists of two shafts mutually connected by a claw coupling and of two bladed wheels. The rotor is mounted withthe stationary part by three rolling-element bearings. The dynamic properties of the rotor are evaluated using the Campbell diagram and frequency response characteristics for the defined range of values of the rotor angular speed.
