Assembly errors can lead to the eccentricity of rotors, further resulting in angular misalignment rotors and inducing some secondary misalignments, such as gears tilt inner ring bearings (TMIRB). Ultimately, these misalignments rubbing faults. However, have not raised significant concern, this article investigates their influence on vibration responses a dual-rotor-gear-bearing system with rubbing. First, finite element model (FEM) is built by using an in-house beam code, nonlinear force...
As one of the most important parts in engine, structure and state rotating blade directly affect normal performance aero engine. In order to monitor engine crack failure ensure flight safety, it is necessary carry out research on dynamic modeling cracked breathing induced vibration mechanisms. This paper summarizes current status dynamics related topics mainly include four aspects: propagation path, mechanical model open cracks, methods blades such as lumped mass model, semi-analytical...
Rubbing between a blade and its coated casing is one of the main failures in aero-engine systems. This paper aims to study effects casings on rubbing-induced dynamic responses considering flexibility blade. Firstly, an actual compressor established by shell element verified experiment ANSYS 19.2 software. Subsequently, new model for proposed based laminated element, comparing natural characteristics calculated Moreover, comprehensive analysis conducted analyze influences model, coating...
