Modeling of non-synchronous rotor vibration
Original language description
In fast-rotating rotors, we can observe non-synchronous vibrations in specific situations. This interesting type of vibration can occur, in aircraft engines. Vibration of aircraft engines must be rigorously monitored and minimized because in terms of safety. Non-synchronous vibrations are not generated directly by rotor imbalance and rotation speed. The effect on the generation of vibrations is mainly clearance in the supports and a lubrication method. In CTU laboratories, such vibrations were measured on a real aircraft engine. This work models the measured engine. The engine is modeled using a nonlinear FEM. Vibration reconstruction can be used to effectively adjust the engine to reduce the magnitude of non-synchronous vibrations.
