Abstract

Misalignment is the most common fault of heavy gas turbine rotor core components.Based on the heavy gas turbine rotor, the finite element dynamic model of rotor misalignment fault of heavy gas turbine is established.The vibration responses of the rotor under parallel misalignment, partial angle misalignment and composite misalignment are calculated through numerical simulation.The results show that the typical dynamic characteristics of rotor misalignment fault are that the peak value of the second harmonic generation increases.At the partial angle misalignment increases by 0.5° the rotor amplitude increases by 20 μm.The dynamic response is more sensitive to the partial angle misalignment.
